Solution please!
As per my computations, option A is 2*1.2 while option B is 1.6-0.4=1.2. So the answer should be A. Can you please explain?

Explanation: This is a ratio. Andy’s height is to Brandon’s height as the length of Andy’s shadow is to the length of Brandon’s shadow: 160/B = 400/300; so B = 120 (don’t forget to change Andy’s height into centimeters like the other measures.) Now, Column A = 2(120)=240, and Column B = 400-160 = 240.
