Question

Mohan and sohan have an age ratio of 15: 8. After 10 years it will be 17:10. Their present ages (in years) are:

Answer 1

Mohan :Sohan = 15:8

Let their ages are 15x & 8x

ATQ
$\frac{15x + 10}{8x + 10} = \frac{17}{10}$
150x+100= 136x+ 170
14x= 70
x=5
Their present ages are
15x= 75 & 8x=40
$mohan = 75 \: \binom{.}{.} sohan = 40$
