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
