Solved Examples

Q1. In an equation, there is always a/an

1. equality sign (=)
2. greater than sign (>)
3. less than sign (<)
4. division sign ( ∏)

Ans. Correct answer is 1

Explanation: An equality sign shows the relationship in which the values on each side of an equation are exactly equal.

Q2. The value of a variable is

1. 0
2. 1
3. fixed
4. not fixed

Ans. Correct answer is 4

Explanation: The value of a variable is not fixed because a variable can take different numerical values.

For example:

• If x = 3, we say that the value of x is 3.
• In other case, if we want to find the value of x in a given equation x - 4 = 2, then the value of x = 2 + 4 = 6.
• Taking another example, if we want to find the value of x in
• 3x = 6, then the value of x = 6/3 = 2.

Hence, we say that the variable x can take different values.

Q3. The equation form of the given statement ‘6 less than a number is 13’ will be

1. x - 6 = 13
2. 6x = 13
3. x - 13 = 6
4. x= 13 - 6

Ans. Correct answer is 1

Explanation: Let the number is x, then x - 6 = 13.

Q4. The statement form of the given equation ‘2x + 6 = 24’ is

1. Twice a number is 24 increased by 6
2. Twice a number increased by 6 is 24
3. Twice a number is 24 and increased by 6
4. Twice a number increased by 24 is 6

Ans. Correct answer is 2

Explanation: 2x = Twice a number of x and, 2x + 6 = twice a number increase by 6

And, 2x + 6 = 24 means twice a number increased by 6 is 24.

Q5. The statement form of the given equation ‘x - 4 = 5’ is

1. Taking away 5 from x gives 4
2. Taking away 4 from 5 gives x
3. Taking away 4 from x gives 5
4. Taking away 5 from 4 gives x

Ans. Correct answer is 3

Explanation: x - 4 = Taking away 4 from x

x - 4 = 24 means taking away 4 from x gives 5.

Q6. If L.H.S. = R.H.S. of an equation, then the equation will be

1. Balanced
2. Unbalanced
3. Constant
4. Wrong

Ans. Correct answer is 1

Explanation: If L.H.S. = R.H.S. of an equation, then the equation is said to be balanced because the value of the left hand side is equal to the value of the right hand side of an equation.

Q7. Subtract 7 from thrice a number the result is 8. The equation form of the above statement is

1. 7x - 2 = 8
2. 8x - 2 = 7
3. 3x - 7 = 8
4. 2x - 8 = 7

Ans. Correct answer is 3

Explanation: Let x be a number

Subtract 7 from trice a number = 3x - 7

Now, The equation form of the given statement is 3x - 7 = 8.

Q8. For the equation 6p - 4 = 8, the solution will be

1. p = 1
2. p = 2
3. p = 3
4. p = 4

Ans. Correct answer is 2

Explanation: Given 6p - 4 = 8 For p = 2,

L.H.S. = 6 x 2 – 4 = 12 - 4 = 8 = R.H.S.

Thus, L.H.S. = R.H.S.

Therefore, p = 2 is a solution for the given equation 6p - 4 = 8.

Q9. Karan says that he has 6 balls more than five times the number of balls Sumit has. If Karan has 36 balls and Sumit has x number of balls, then the equation form for this statement is

1. 5x + 6 = 36
2. 5x + 36 = 6
3. 5x - 6 = 36
4. 5x - 36 = 6

Explanation: Let Sumit has x balls

Then according to given statement, the equation form will be

5x + 6 = 36.

Q10. If the sum of three consecutive even numbers is 78 then the numbers will be

1. 10, 12 an 14
2. 16, 18 and 20
3. 22, 24 and 26
4. 24, 26 and 28

Ans. Correct answer is 4

Explanation: Let us assume three consecutive even numbers are x, x + 2 and x + 4

Therefore, according to question x + (x + 2) + (x + 4) = 78

3x + 6 = 78

3x = 78 – 6 = 72

x = 24(Divide both side by 3)

Thus, the numbers are

x = 24, x + 2 = 26 and x + 4 = 28.
