Question

A team of freshers should be divided into two teams. There are totally 25 members in which team A should contain 14 members and team B should contain 11 members. The average age of team A is 35 and the average of 25 members is 45. What is the average age of team B? ​

Answer 1

Step-by-step explanation:

Team A = 20x

Team B = 30y

So combined average is

--> (20x + 30y)/(x+y) = 26;

--> 26x + 26y = 20x + 30y;

Hence 6x=4y

Therefore x/y = 2/3
