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 ?

Answer» 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.
