Question

Sushma is now 15 years older than Vijay but in 3 more years Sushma will be 8 times as old as Vijay was 3 years ago.how old are they now​

Answer 1

• 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.
