Question

Sushil is 6 years older than Brian. Caroline is 5 years younger than Brian. If the total of their ages is 64, how old is the youngest of them

Answer 1

Call Brian's age: x, then Sushil's age is: x + 6 and Caroline's age is: x-5

So we have: x + (x + 6) + (x-5) = 64

=> 3x +1 = 64 => x = 63/3 = 21

the youngest of them: 21-5 = 16
