The average weight of the group of 12 players increases by 1.5 kg when a new player replaces a player who weight 63 kg. What is the weight of the new player?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 81 kg.
Given that
The average weight of the group of 12 players increases by 1.5 kg
The weight of the replaced player = 63 kg
According to the question,
Increased weight = 12 × 1.5 = 18 kg
Hence,
The weight of new player = 63 + 18 = 81 kg
