Right Answer is: B
SOLUTION
Given:
Sum of three consecutive odd integers = 39
Calculation:
Let x, x + 2, x + 4 be the three consecutive odd integers.
Sum of three consecutive odd integers = 39
⇒ x + (x + 2) + (x + 4) = 39
⇒ 3x + 6 = 39
⇒ 3x = 33
⇒ x = 11
∴ The integers are 11, 13 and 15.
∴ Their product = 11 × 13 × 15 = 2145
