Question
There are 45 players in a sports camp with an average age of 26 years. 5 more players join, decreasing the average to 25. Find the average age of the new players.
Solution
Initial sum = 45 × 26 = 1170 years
New total = 50
New average = 25
New sum = 50 × 25 = 1250 years
Sum of new = 1250 - 1170 = 80 years
Average = 80 ÷ 5 = 16 years
