Question

5 yrs ago father was 7 times sons age. after 5 yrs he will be 3 times sons age find son's percent age?​

Answer 1

$\huge \star \underline\bold \red{ANSWER} \star$

Let present age of father be x and son be y

After 5 years, father's age = 5+x

After 5 years, son's age = 5+y

By the question

(5+x) = 3(5+y) (i)

(x-5) = 7(y-5) (ii)

Solve (i) and (ii)

we get

father's present age = 40 years

and son's present age = 10 years
