Answer 1

$\huge\bf{Question}$

Madhu is 15 yrs older than her brother vijay after 3 yrs she will be 8 time as old as vijay was 3 yrs ago find their present ages.

$\huge\bf{Answer}$

Let Vijay's present age be 'x'.

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

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

Vijay's age 3 years ago was X-3

Given, Madhu'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.

Madhu is 21 years old.
