According to the video lectures, we should be ignoring the negative roots, but the answers guide in the 5lb book suggests otherwise(for this question), and marks D as correct. What should i do in such a case?
I guess video lecture tells you to ignore negative roots in some cases. However, in this example as you can see you can have
- g = 28
- g = -28
In the first case Quantity A = Quantity B. In the second case Quantity A < Quantity B. Thus , the correct answer is D.
