Practice Data Sufficiency –

The average weight of a class of 100 students is 45 kg. The class consists of two sections, I and II, each with 50 students. The average weight, WI, of Section I is smaller than the average weight, WII, of Section II. If the heaviest student, say Deepak, of Section II is moved to Section I, and the lightest student, say Poonam, of Section I is moved to Section II, then the average weights of the two sections are switched, i.e., the average weight of Section I becomes WII and that of Section II becomes WI.

What is the weight of Poonam?

A. WII– WI = 1.0

B. Moving Deepak from Section II to I (without any move from I to II) makes the average weights of the two sections equal.
