Problem Solving: Averages Practice MCQ

Question Statement:

When a student weighing 45 kgs left a class, the average weight of the remaining 59 students increased by 200 g. What is the average weight of the remaining 59 students?

56.8

58.2

52.2

Explanation:

Correct Answer: A

Let the average weight of the 59 students be A.

Therefore, the total weight of the 59 of them will be 59 A.

The questions states that when the weight of this student who left is added, the total weight of the class

= 59A+45

When this student is also included, the average weight decreases by 0.2 kgs.

59A+45/60=A−0.2

⇒59A+45=60A−12

⇒45+12=60A−59A

⇒A=57
