played 35 games and won 94.3% of them. What is the group average? (Ans. 80%]

Aving table given the made population of Varanasi and Agra in 2011.

Answer 2

Given:

Number of games played by A = 45

Number of games played by B = 40

Number of games played by C = 35

Win percentage of A = 73.3%

Win percentage of B = 75%

Win percentage of A = 94.3%

To find:

The average of the group.

Solution:

The average = Sum of win percentage/ total number of teams

= (73.3% + 75% + 94.3%)/ 3

= 80.67% (rounded off to two decimal places)

Therefore the average of win percentage is 80.67%.
