What is the greatest of 3 consecutive integers whose sum is 24 ? Options.
A) 3
B) 76
C) 8
D) 9
E) 10

Rationale: explanation : the sum of three consecutive integers can be written as n + ( n + 1 ) + ( n + 2 ) = 3 n + 3 if the sum is 24 , we need to solve the equation 3 n + 3 = 24 ; = > 3 n = 21 ; = > n = 7 the greatest of the three numbers is therefore 7 + 2 = 9 answer : d ) 9
Answer: D
