1. The average weight of 3 men is 53 kg. None of them weights less than 51 kg. What is the maximum possible weight (in kg) of a person in that group?
- A. 57
- B. 57
- C. 57
- D. 57
Answer: Option A
Explanation:
The total weight of them = 53×3 = 159 kg
Minimum weight possible for any 2 of them = 51×2 = 102 kg
Maximum weight of any 1 of them = 159 - 102 = 57 kg
