The product of three consecutive even numbers when divided by 8 is 720. The product of their square roots is :

12 sqrt(10)
24 sqrt(10)
120
none of these

Correct Answer: 24 sqrt(10)

Explanation:

Let the numbers be x, x + 2 and X + 4.

Then, x(x + 2)(x +4) / 8 = 720 => x(x + 2)(x +4) = 5760.

√x * √(x + 2) * √(x +4) = √x(x +2)(x + 4 ) = √5760 = 24√10.
