Q1 If a number is 10x + y and the digits are reversed, the new number is:

(A) x + 10y

(B) 10y + x

(C) y – x 

(D) x – y

Q2. Write the following numbers in generalised

form.

(i) ab

(ii) 85

(A) (i) ab = 10 × a + 1 × b = 10a + b(ii) 85 = 10 ×

8 + 1 × 5 = 10 × 8 + 5

(B) (i) ab = 10 × a + 1 × b = 10a + b(ii) 85 = 10 ×

8 + 1 × 5 = 10 × 80+ 5

(C) (i) ab = 10 × a + 1 × b = 10a + b(ii) 85 = 10 ×

8 + 1 × 5 = 10 × 1 + 20×5

(D) (i) ab = 1 × a + 1 × b = 10a + b(ii) 85 = 10 × 8

+ 1 × 5 = 10 × 8 + 5

explanation of A.

(B) A and R are true, but R is not the correct

explanation of A.
