Present age of Amit is twice of Ram's present age.  After 5 years, Ram's age will be 4 times of the Sonu's present age.  If Sonu celebrated his 6th birthday 7 years ago, then what will be the present age of Amit?

94

Sonu's present age = 6 + 7 = 13 years

Ram's age after 5 years = 13 × 4 = 52 years

Present age of Ram = 52 - 5 = 47 years

Amit's present age = 47 × 2 = 94 years
