Question

The present age of the mam is 3times that of his son. Ten years ago , he was 5times as old his then age of the son 3 years later is​

Answer 1

Step-by-step explanation:

Let present age of son be 'x'

then present age of man is 3x

Ten years ago,

age of son = x -10

age of man = 3x - 10

3x - 10 = 5(x-10)

3x - 10 = 5x - 50

50 - 10 = 5x - 3x

40 = 2x

x = 20

present age of son is 20 years

age of son 3 years later = x + 3 = 20 + 3 = 23 years
