Question 36: If a, b and c are consecutive integers, a < b < c, and a + b + c = 96, what is the value of b?

(a) 30

(b) 31

(c) 32

(d) 33

(e) 34

Solution: If a, b and c are consecutive numbers, b = a + 1 and c = a + 2.

Then, a + (a + 1) + (a + 2) = 96, so 3·a + 3 = 96.

a = (96 - 3)/3 = 31.

b = a + 1 = 32.
