Correct Answer - Option 5 : 85 kg
Given
Average weight of a cricket team of 10 players = 30 kg
Formula used
Average = (Sum of values/Number of values)
Calculation
Total weight of 10 players = 30 × 10 = 300 kg.
Total weight of 11 person (10 players + 1 coach) = 35 × 11 = 385 kg.
Weight of coach = 385 – 300 = 85 kg.
∴Weight of coach is 85 kg.
