**Question 5:**

The question is followed by two statements A and B. Indicate your response based on the following directives.

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, W_{I }, of Section I is smaller than the average weight W_{II }, of the 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 W_{II} and that of Section II becomes W_{I }. What is the weight of Poonam?

A: W_{II }– W_{I }=1.0.

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