Question

Sanjay will be 3 times as old as he was 4 years ago after 18 years find his present age

Answer 1

Let Sanjay's present age = x yrs

Then His age after 18 yrs will be = (x+18)yrs

Sanjay's age 4 yrs ago = (x-4)yrs

Now...According to question,

Sanjay's age after 18 yrs =3 times of his age 4 yrs ago

x+18 = 3 (x-4)

x+18 = 3x - 12

18-12 = 3x - x

6 = 2x

x = 6/2

x = 3

Sanjay's present age is 3 yrs
