If the product of three consecutive integers is 210, the sum of integer is --

A 12
B 14
C 15
D 18

Correct Answer: 18

Let,the three numbers are 5X, 6X, 7X                                                                                                   Here,produt of three consecutive integers is 210                       So 5X × 6X × 7X= 210                               210X  = 210                                                                                                                                                         X=1        The numbers are 5, 6,7; so their sum is 5+6+7= 18Answer: 18
