Question

Mother is 25 years older than her son. Find son's age if after 8 years ratio of son's age and mother's age will be 4/9

Answer 1

it's 53 years

hope that helps

Answer 2

Let, son's present age be = x

then, Mother's present age be = x+25

After Eight years the ratio of their ages = $\bf\frac{4}{5}$

After eight years,

Son's age = x+8

Mom's age = x+25+8 = x+33

Ratio,

$\frac{x + 8}{x + 33} = \frac{4}{5}$

$9x + 72 = 132 + 4x$

$5x = 60$

$x = 12$

Therefore, the son's present age is ,$\bf{12\:years.}$
