12 year old Manick is three times as old as his brother Rahul. How old will Manick be when he is twice as old as Rahul ?

14 years

16 years

18 years

20 years

Manick's present age = 12 years, Rahul's present age = 4 years.

Let Manick be twice as old as Rahul after x years from now.

Then, 12 + x = 2 (4 + x) => 12 + x = 8 + 2x => x = 4.

Hence, Manick's required age = 12 + x = 16 years.
