1.	Sushma is now 15 years older than Vijay but in 3 more years she will be 8 times as old as Vijay was 3years ago. How old are they now?
Answer» Let Vijay's present age be 'x'. Then, Sushma's present age will be X+15 Sushma's age after 3 years will be [(X+15) + 3] = X+18 Vijay's age 3 years ago was X-3 Given, Sushma's age 3 years from now will be equal to 8 times of what Vijay's age was 3 years back. Therefore, X+18 = 8 (X-3) X + 18 = 8X - 24 8X - X = 18 + 24 7X = 42 X = 6 Therefore, their present ages are as follows: Vijay is 6 years old. Sushma is 21 years old.

Answer»

Let Vijay's present age be 'x'.

Then, Sushma's present age will be X+15

Sushma's age after 3 years will be [(X+15) + 3] = X+18

Vijay's age 3 years ago was X-3

Given, Sushma's age 3 years from now will be equal to 8 times of what Vijay's age was 3 years back.

Therefore, X+18 = 8 (X-3)

X + 18 = 8X - 24

8X - X = 18 + 24

7X = 42

X = 6

Therefore, their present ages are as follows:

Vijay is 6 years old.

Sushma is 21 years old.
