Question
Asim is four years older than his brother Basu who is
thrice as old as Chetan. If Asim is four times as old as Chetan, then how old (in years) is Basu?Solution
Let Chetan's age be c years. Then, Basu's age = 3c years. Asim's age = 3c + 4 years (4 years older than Basu). Also, Asim's age = 4c years (4 times Chetan). Therefore, 4c = 3c + 4 => c = 4. So, Basu's age = 3c = 3*4 = 12 years.
