A is 4 years older than B who is three times as old as C. The total of the ages of A, B and C is 88 years. What is the average of A and C ages?

OPtion

1) 26 years
2) 24 years
3) 30 years
4) 22 years
5) 20 years
6) 25 years
7) 28 years
8) 18 years
9) 32 years
10)None of these

Solution

Let’s assume Age of B be B years
Age of A = B+4
Age of C = B/3

Total age = B + 4 + B + B/3 = 88
Solving 7B/3 = 84
B = 12*3 = 36
A = B+4 = 40
C = B/3 = 12

Average = (40+12)/2 = 26 years
