Step-by-step explanation:
Assume son’s age is x, then Father age is 5x.
If Father age is 5x, mother age is 4x.
After 2 years son & mother age can be as follows(Mother age : son age → 3: 10)
3*(4x + 2) = 10(x + 2)
12x + 6 = 10x + 20
2x = 14
x = 7
So the present age of son is 7 years, Father is 35 and mother is 28 years.
