1. How much money will be required to buy 400, Rs.12.50 shares at a premium of Rs.1?
Solution:
Given, The number of shares required to be bought = 400 And, Rs 12.50 shares at a premium of Rs 1 means; Nominal value of the share is Rs. 12.50 And its market value = Rs 12.50 + Rs 1 = Rs 13.50 So, the money required to buy 1 share = Rs 13.50 Thus, The money required to buy 400 shares = 400 x Rs 13.50 = Rs 54002. How much money will be required to buy 250, Rs.15 shares at a discount of Rs.1.50?
Solution:
The number of shares to be bought is 250. And, Rs 15 shares at a discount of Rs 1.50 means Nominal value of the share is Rs 15 and Its market value = Rs 15 – Rs 1.50 = Rs 13.50 Thus, The money required to buy 250 shares = 250 x Rs 13.50 = Rs 33753. A person buys 120 shares at a nominal value of Rs 40 each, which he sells at Rs 42.50 each. Find his profit and profit percent.
Solution:
Given, The nominal value of each share is Rs 40 So, the nominal value of 120 shares = Rs 40 x 120 = Rs 4,800 And, the market value of 120 shares = Rs 42.50 × 120 = Rs 5,100 Thus, his profit = Rs 5,100 – Rs 4,800 = Rs 300 And the profit percentage is given by, Profit (%) = 300/4800 x 100 = 6.25 %4. Find the cost of 85 shares of Rs 60 each when quoted at Rs 63.25.
Solution:
Given, Market value of 1 share = Rs 63.25 So, the market value of 85 shares = Rs 63.25 x 85 = Rs 5,376.255. A man invests Rs800 in buying Rs5 shares and when they are selling at a premium of Rs1.15, he sells all the shares. Find his profit and profit percent.
Solution:
Nominal value of 1 share = Rs 5 Market value 1 share = Rs 5 + Rs 1.15 = Rs6.15 Total money invested = Rs 800 So, the number of shares purchased = 800/5 = 160 And, Market value of 160 shares = 160 x 6.15= Rs 984 Thus, his profit = Rs 984 – Rs 800 = Rs 184 And the profit percentage is given by Profit (%) = 184/800 x 100 = 23 %6. Find the annual income derived from 125, Rs.120 shares paying 5% dividend.
Solution:
Given, The nominal value of 1 share = Rs 120 So, the nominal value of 125 shares = 125 x Rs 120 = Rs 15,000 Now, Dividend = 5 % of Rs 15,000 ⇒ 5/100 x 15000 = Rs 750 Thus, the annual income is Rs 7507. A man invests Rs 3,072 in a company paying 5% per annum, when its Rs 10 share can be bought for Rs 16 each. Find:
(i) his annual income
(ii) his percentage income on his investment.
Solution:
Given, Market value of 1 share = Rs 16 Nominal value of 1 share= Rs 10 And the money invested = Rs3,072 So, the number of shares purchased = 3072/16 = 192 And, the nominal value of 192 shares = Rs 10 x 192 = Rs 1,920 Therefore, (i) The annual income = 5 % of Rs 1,920 = 5/100 x 19201. A man buys 75, Rs 100 shares paying 9 percent dividend. He buys shares at such a price that he gets 12 percent of his money. At what price did he buy the shares?
Solution:
Given, Nominal value of 1 share = Rs100 So, the nominal value of 75 shares = 100 x 75 = Rs 7,500 And, Dividend % = 9 % Thus, dividend = 9 % of Rs 7,500 = 9/100 x Rs 7,500 = Rs 675 Let’s consider the market price of 1 share = Rs y Then the market price of 75 shares = Rs 75y And, Profit % on investment = 12% 12% of 75y = Rs 657 12/100 x 75y = Rs 657 y = Rs 75 Therefore, the price of his shares is Rs 75 each2. By purchasing Rs 25 gas shares for Rs 40 each, a man gets 4 percent profit on his investment. What rate percent is the company paying? What is his dividend if he buys 60 shares?
Solution:
Given, Nominal value of 1 share = Rs25 Market value of 1 share = Rs40 And, the profit% on investment = 4% Then profit on 1 share = 4% of Rs 40 = Rs 1.60 Thus, Dividend % = 1.60/25 x 100 = 6.4% Next, If the number of shares purchased = 60 Then, the dividend on 60 shares = 60 x Rs 1.60 = Rs 963. Hundred rupee shares of a company are available in the market at a premium of Rs 20. Find the rate of dividend given by the company, when a man’s return on his investment is 15%.
Solution:
Given, Nominal value of 1 share = Rs 100 And the market value of 1 share = Rs100 + Rs 20 = Rs120 (as the premium is Rs 20) Also given, the profit % on investment of 1 share = 15% Then profit = 15% of Rs 120 = Rs 18 Therefore, Dividend % = 18/100 x 100 = 18%4. Rs 50 shares of a company are quoted at a discount of 10%. Find the rate of dividend given by the company, the return on the investment on these shares being 20 percent.
Solution:
Given, Nominal value of 1 share = Rs 50 Discount on each share = 10 % So, the market value of 1 share = Rs50 – 10% of Rs50 = Rs 50 – Rs 5 = Rs 45 Also given, Profit % on investment = 20% Then the profit on 1 share = 20% of Rs 45 = Rs 9 Therefore, Dividend % = 9/50 x 100 = 18 %5. A company declares 8 percent dividend to the shareholders. If a man receives Rs 2,840 as his dividend, find the nominal value of his shares.
Solution:
Given, Dividend % = 8 % And, the dividend is Rs 2,840 Let the nominal value of shares be Rs y Then, 8% of y = Rs 2,840 (8/100) x y = Rs 2,840 y = Rs 35,500 Thus, the nominal value of the man’s share is Rs 35,5006. How much should a man invest in Rs 100 shares selling at Rs 110 to obtain an annual income of Rs 1,680, if the dividend declared is 12%?
Solution:
From the question, Nominal value of 1 share = Rs100 And, the market value of 1 share = Rs110 Let the number of shares purchased = n Then the nominal value of n shares = Rs (100n) Dividend % = 12% Given that the dividend = Rs1,680 12 % of 100n = Rs 1,680 12/100 x 100n = Rs 16807. A company declares a dividend of 11.2% to all its share-holders. If its Rs 60 share is available in the market at a premium of 25%, how much should Rakesh invest, in buying the shares of this company, in order to have an annual income of Rs 1,680?
Solution:
Given, Nominal value of 1 share = Rs60 Market value of 1 share = Rs 60 + 25% of Rs 60 = Rs 60+ Rs 15= Rs 75 Let the number of shares purchased be n Then, the nominal value of n shares = Rs (60n) Dividend % = 11.2% Given that the dividend = Rs 1,680 So, 11.2% of 60n = Rs 1,680 11.2/100 x 60n = Rs 1,6808. A man buys 400, twenty-rupee shares at a premium of Rs 4 each and receives a dividend of 12%. Find:
(i) the amount invested by him.
(ii) his total income from the shares.
(iii) percentage return on his money.
Solution:
Given, The nominal value of 1 share = Rs 20 Market value of 1 share = Rs 20 + Rs 4 = Rs 24 No. of shares purchased = 400 Nominal value of 400 shares = 400 x 20 = Rs 8,000 (i) Market value of 400 shares = 400 x 24 = Rs 9,600 (ii) Dividend% = 12% Dividend = 12% of Rs 8,000 = 12/100 x Rs 8,000 = Rs 960 Thus, the total income from the shares is Rs 960 (iii) Percentage return on his money is Return % = income/investment x 100 = (960/9600) x 100 = 10%9. A man buys 400, twenty-rupee shares at a discount of 20% and receives a return of 12% on his money. Calculate:
(i) the amount invested by him.
(ii) the rate of dividend paid by the company.
Solution :
Given, The nominal value of 1 share = Rs 20 Market value of 1 share = Rs20 – (20% of Rs 20) = Rs 20 – Rs 4 = Rs 16 Number of shares purchased = 400 Nominal value of 400 shares = 400 x 20 = Rs 8,000 (i) Market value of 400 shares = 400 x 16 = Rs 6,400 (ii) Return% = 12% Income = 12% of Rs 6,400 = 12/100 x Rs 6,400 = Rs 768 And, (iii) The rate of dividend is Dividend % = (income/ nominal value) x 100 = (768/ 8000) x 100 = 9.6 %10. A company, with 10,000 shares of Rs 100 each, declares an annual dividend of 5%.
(i) What is the total amount of dividend paid by the company?
(ii) What should be the annual income of a man who has 72 shares in the company?
(iii) If he received only 4% of his investment, find the price he paid for each share.
Solution:
Given, Nominal value of 1 share = Rs100 Then, nominal value of 10,000 shares =10,000 x Rs 100= Rs 10,00,000 (i) Dividend %= 5% Dividend = 5% of Rs 10,00,000 = 5/100 x Rs 10,00,000 = Rs 50,000 Thus, a dividend amount of Rs 50,000 is paid by the company. (ii) Nominal value of 72 shares = Rs100 x 72 = Rs7,200 Dividend = 5% of Rs7,200 = 5/100 x Rs 7,200 = Rs 360 Thus, the annual income of the man is Rs 360 (iii) Let’s consider the market value of 1 share = Rs y Then market value of 10,000 shares = Rs (10,000y) And the return% = 4% So, 4% of Rs (10,000y) = Rs 50,000 = 4/100 x 10,000y = Rs 50,000 y = Rs 125 Thus, the price for each share is Rs 1251. By investing Rs.45,000 in 10% Rs.100 shares, Sharad gets Rs.3,000 as dividend. Find the market value of each share.
Solution:
We know that, Annual income from 1 share = 10% of Rs 100 = Rs 10 Given, the total income = Rs 3000 (as dividend) Hence, The number of shares bought = Total annual income/ Annual income from 1 share = 3000/10 = 300 Therefore, The market value of one share = Total investment/ Number of shares = 4500/300 = Rs 1502. Mrs. Kulkarni invests Rs.1, 31,040 in buying Rs.100 shares at a discount of 9%. She sells shares worth Rs.72,000 at a premium of 10% and the rest at a discount of 5%. Find her total gain or loss on the whole.
Solution:
Given, Investment = Rs 1,31,040 Nominal value of 1 share = Rs 100 Discount = 9% of Rs 100 = Rs 9 So, the market value of 1 share = Rs 100 – Rs 9 = Rs 91 Then, the number of shares purchased = Investment/ market value of 1 share = 1,31,040/ 91 = 1440 Number of shares worth Rs 72,000 = 72,000/100 = 720 Now, Mrs. Kulkarni sells 720 shares at a premium of 10% Then, the market value of 1 share = Rs 100 + Rs 10 = Rs 110 So, the selling price of 720 shares = 720 x Rs 110 The number of remaining shares = 1440 – 720 = 720 And, she sells 720 shares at a discount of 5% Now, the market value of 1 share = Rs 100 – Rs 5 = Rs 95 The selling price of 730 shares = 720 x Rs 95 = Rs 68,400 Total selling price = Rs(79,200 + 68,400) = Rs 1,47,600 Thus, the total gain = Total selling price – Total investment = Rs (1,47,600 – 1,31,040) = Rs 165603. A man invests a certain sum on buying 15% Rs.100 shares at 20% premium. Find :
(i) His income from one share
(ii) The number of shares bought to have an income, from the dividend, Rs.6480
(iii) Sum invested
Solution:
(i) Dividend on one share = 15% of Rs 100 = Rs (15/100 x 100) = Rs 15 Hence, the income from one share is Rs 15 (ii) Number of shares bought by the man = annual income/ dividend on one share = 6480/ 15 = Rs 432 (iii) Given that the man bought shares of Rs 100 at 20% premium, the market value of one share = Rs (1 + 20/100) x 100 = Rs (120/100 x 100) = Rs 120 His total investment = number of shares x market value of one share = 432 x Rs 120 = Rs 51, 8404. Gagan invested 80% of his savings in 10% Rs.100 shares at 20% premium and the rest of his savings in 20% Rs.50 shares at Rs.20% discount. If his incomes from these shares is Rs.5,600 calculate:
(i) His investment in shares on the whole
(ii) The number of shares of first kind that he bought
(iii) Percentage return, on the shares bought on the whole.
Solution:
(i) Let’s assume the total savings be Rs x (which is the investment) For the 1 st part – 80% of his savings Nominal value of each share = Rs 100 Market value of each share = 100 + 20% Rs 100 = 100 + 20 = Rs 120 So, the number of shares bought will be = 0.8x/120 Dividend on each share = 10% of 100 = Rs 10 Hence, the total dividend = 10 x (0.8x/120) = Rs 0.8x/12 Now, the 2 nd part (remaining 20% of savings) Nominal value of each share = Rs 50 Market value of each = 50 – 20% Rs 50 = 50 – 10 = Rs 40 So, the number of shares bought = 0.2x/ 40 Dividend on each share = 20% of 50 = Rs 10 Hence, the total dividend = 10 x 0.2x/40 = Rs 0.2x/4 Given that dividend (incomes) from both the investments are Rs 5600 So, we have Rs 0.8x/12 + Rs 0.2x/4 = 5600 (0.8x + 0.6x)/12 = 5600 x = (5600 x 12)/ 1.4 x = 48,000 Therefore, the investment in shares together as his savings is Rs 48,000 (ii) Now, the number of shares bought = 0.8x/120 = (0.8 x 48,000)/ 120 = Rs 320 (iii) The total dividend or the return = 0.8x/12 + 0.2x/4 = 0.8(48,000)/12 + 0.2(48,000)/45. Ashwarya bought 496, Rs.100 shares at Rs.132 each, find:
(i) Investment made by her
(ii) Income of Ashwarya from these shares, if the rate of dividend is 7.5%.
(iii) How much extra must Ashwarya invest in order to increase her income by Rs.7,200
Solution:
Given, (i) The nominal value of each share = Rs 100 Market price of each share = Rs 132 Number of shares bought = 496 So, the investment made by her = 496 x Rs 132 = Rs 65,472 (ii) Dividend on 1 share = 7.5% of Rs 100 = Rs 7.5 Thus, the income of Ahwarya from these shares = 496 x 7.5 = Rs 3,720 (iii) If she wants to increase her income by Rs 7,200 Then the number of shares she should buy = increase in the income/ income of one share = 7,200/7.5 = 960 Therefore, she should invest an extra of = 960 x Rs 132 = Rs 1,26,7206. Gopal has some Rs.100 shares of company A, paying 10% dividend. He sells a certain number of these shares at a discount of 20% and invests the proceeds in Rs.100 shares at Rs.60 of company B paying 20% dividend. If his income, from the shares sold, increases by Rs.18,000, find the number of shares sold by Gopal.
Solution:
Given, The nominal value of each share = Rs 100 Rate of dividend = 10% Dividend on each share = 10% of Rs 100 = Rs 10 Then, the dividend on x shares will be Rs 10x Selling price of each share = Rs 100 = 20% of Rs 100 = Rs 80 And, the amount obtained on selling x shares = Rs 80x Given that, the proceeds are invested in Rs 100 shares at Rs 60 of company B paying 20% dividend Now, Nominal value of each share = Rs 100 Market value of each share = Rs 60 So, the number of shares bought by the man = amount obtained/ Market value of each share = 80x/60 = 4x/3 Dividend on each share = 20% of Rs 100 = Rs 20 So the total dividend received = Divided on each share x number of shares = 20 x 4x/3 = 80x/3 Given, the increase in the income = Rs 18,000 Thus, 80x/3 – 10x = 18,000 50x/3 = 18,000 x = Rs 1080 Therefore, the number of shares sold by Gopal is Rs 10807. A man invests a certain sum of money in 6% hundred-rupee shares at Rs.12 premium. When the shares fell to Rs.96, he sold out all the shares bought and invested the proceed in 10%, ten-rupee shares at Rs.8. If the change in his income is Rs.540, Find the sum invested originally
Solution:
Let’s assume the original sum invested to be Rs x Then the number of Rs 100 shares purchased at premium of Rs 12 will be = x/ (100 + 12) = x/112 Given, The income per original share is 6% = Rs 6 So, the total income = (Number of shares) x (earning per share) = (x/112) x 6 = 3x/56 Proceeds from the sale of original shares at Rs 96 per share = (number of shares) x 96 = x/112 x 96 = 6x/7 Number of Rs 10 shares purchased at Rs 8 per share from the proceeds of original shares = (Proceeds from sale of original shares)/8 = (6x/7)/8 = 3x/28 Income per new share of Rs 10 at 10% = 10/100 x 10 = Rs 1 Thus, the total income from the new shares = Number of shares x income per share = 3x/28 x 1 = 3x/28 The change in income is Rs 540 (given) Income from old shares – Income from new shares = Rs 540 So, 540 = 3x/28 – 3x/56 = 3x/56 x = 540/ (3/56) = 10, 080 Therefore, the original sum invested is Rs 10,0808. Mr. Gupta has a choice to invest in ten-rupee shares of two firms at Rs13 or at Rs16. If the first firm pays 5% dividend and the second firm pays 6% dividend per annum, find:
(i) which firm is paying better.
(ii) if Mr. Gupta invests equally in both the firms and the difference between the returns from them is Rs 30, find how much, in all, does he invest.
Solution:
(i) The first firm: Nominal value of 1 share = Rs 10 Market value of 1 share = Rs 13 Dividend = 5% of Rs 10 = Rs 0.50 Thus, the income % = Income/ Investment x 100 = 0.50/13 x 100 = 3.846 % Now, The second firm: Nominal value of 1 share = Rs 10 Market value of 1 share = Rs 16 Dividend % = 6 % Thus, income % = income/ investment x 100 = 0.60/ 16 x 100 = 3.75 % Therefore, the first firm is paying better than second firm (ii) Let money invested in each firm = Rs y For 1 st firm Number of shares purchased = y/13 shares Total dividend = Rs 0.50 x y/13 = Rs y/26 For 2 nd firm Number of shares purchased = y/16 shares Total dividend = Rs 0.60 x y/16 = Rs 3y/80 Given the difference of both dividend = Rs 30 y/ 26 – 3y/ 80 = Rs 30 y/ 1040 = Rs 30 y = Rs 30 x 1040 = Rs 31,200 Therefore, total money invested in both firm = Rs 31,200 x 2 = Rs 62,4009. Ashok invested Rs.26,400 in 12%, Rs.25 shares of a company. If he receives a dividend of Rs.2,475, find the:
(i) number of shares he bought.
(ii) market value of each share.
Solution:
(i) Given, total dividend = Rs 2,475 So, the dividend on each share = 12% of Rs 25 = 12/100 x Rs 25 = Rs 3 Thus, the number of shares bought = Total dividend/ Dividend on 1 share = 2475/ 3 = 825 (ii) Market value of 825 shares = Rs 26,400 Therefore, market value of each share = total investment/ number of shares = 26400/825 = Rs 3210. A man invested Rs45,000 in 15% Rs100shares quoted at Rs125. When the market value of these shares rose to Rs140, he sold some shares, just enough to raise Rs8,400. Calculate:
(i)the number of shares he still holds;
(ii)the dividend due to him on these remaining shares.
Solution:
(i) Total investment = Rs 45,000 And the market value of 1 share = Rs 125 Thus, the number of shares purchased = 45000/125 = 360 shares Nominal value of 360 shares = Rs 100 x 360 = Rs 36,000 Now, let the number of shares sold be n Then, the sale price of these n shares is = Rs 8,400 So, n = 8400/140 = 60 shares Thus, the number of shares he still holds is 360 – 60 = 300 (ii) Nominal value of 300 shares = Rs 100 x 300 = Rs 30,000 And, dividend% = 15% Dividend = 15% of Rs 30,000 = 15/100 x Rs 30,000 = Rs 4,500
