Sunil's age is four times his son's age.Five years ago Sunil's age was seven times his son's age.Find their present age

Answer 1

HEYA MATE, HERE IS UR ANSWER ___________________________

Let the son's age be x years.
Sunil's age = 4x years.

Five years ago,
Son's age =x-5
Sunil's age=4x-5................. (1)

BUT ACCORDING TO THE QUESTION

Sunil's age=7 (x-5)............. (2)

From (1) and (2)
4x-5=7 (x-5)
4x-5=7x-35
-5+35=7x-3x
30=4x
30/4=x
7.5=x.

so,Son's age = 7.5 years

Sunil's age =4×7.5
=30 years.
