Q)

The product of three consecutive even numbers is 4032. The product of the first and the third number is 252. What is five times the second number?

    • Explanation

    Let the even consecutive numbers are 2n – 2, 2n, 2n + 2

    ⇒ (2n – 2)×(2n)×(2n + 2) = 4032   ---Eq(1)

    The Product of 1st even number 3rd even number = 252

    Substitute this in equation ---Eq(1)

    ⇒ 252×2n = 4032 ⇒ n = 8

    ∴ Numbers are 14, 16, 18

    ∴ Five times of second number is = 5×16=80

    Hence, Option A is correct.
