Question

The product of three consecutive even numbers when divided by 32 is 720. The product of their square roots is:

• A. 2√10
• B. 24√10
• C. 36√10
• D. 48√10
• E. None of these

Answer 1

The correct option is D

48√10

Let the three consecutive even numbers be x, x+2, x+4

$x\left(x+2\right)\left(x+4\right)=32\times 720$

$\sqrt{x\left(x+2\right)\left(x+4\right)}=48\sqrt{10}$
