Detailed Solution
Download Solution PDFGiven:
The average weight of a kabaddi team of 121 players = 71 kg
The average weight increases by 1 kg when the manager is included
Formula used:
New average = (Total weight of players + Weight of manager) / (Number of players + 1)
Calculation:
Total weight of the team (players only) = 121 × 71 = 8591 kg
New average weight = 71 + 1 = 72 kg
⇒ (Total weight of players + Weight of manager) / (121 + 1) = 72
⇒ (8591 + Weight of manager) / 122 = 72
⇒ 8591 + Weight of manager = 72 × 122
⇒ 8591 + Weight of manager = 8784
⇒ Weight of manager = 193 kg
∴ The correct answer is option (3).
