1. The average weight of teacher is also included, then the average weight is increased by 200 grams. Find the weight of the teacher?
- A. 93.6 kg
- B. 93.6 kg
- C. 93.6 kg
- D. 93.6 kg
Answer: Option A
Explanation:
Total weight including teacher = 09.2x18 = 1623.6
Total weight of 17 students = 90x17 = 1530
So, the weight of teacher = 1623.6 - 1530 = 93.6 kg
