If 6 years are subtracted from the present age of Gagan and the remainder is divided by 18, then the present age of his grandson Anup is obtained. If Anup is 2 years younger to Madan whose age is 5 years, then what is Gagan's present age?
60 years
Anup's age = (5 - 2) years = 3 years. Let Gagan's age be 'x' years.
Then, x−618=3
⇒ x - 6 = 54
⇒ x = 60 years
