Six consecutive whole numbers are given ; the sum of the first three numbers is 27. What is the sum of the last three numbers ?

A 36
B 33
C 32
D 30

Correct Answer: 36

Let the numbers be (x - 3), (x - 2), (x - 1), x, (x + 1), (x + 2) respectively. Now, (x - 3) + (x - 2) + (x - 1) = 27 or, 3x - 6 = 27 or, 3x = 33 or,  x = 11. So,  x + (x + 1) + (x + 2) = 11 + 12 + 13 = 36.
