Question

The sum of three consecutive integers is 39. Which of the following is the largest among the three?
(a) 12 (b) 15
(c) 13 (d) 16
(e) None of these

Answer 1

(e) Let the three consecutive integers be x, x + 1 and x + 2 

According to the question,

 x + x + 1 + x + 2 = 39 

or, 3x + 3 = 39 

or, 3x = 39 – 3 = 36 

or, x = 36 /3 = 12 

Required largest number = x + 2 = 12 + 2 = 14
