Question
The average age of a team of 20 men is 36 years. If the
total age of a group of 16 women is 20% less than the total age of the team of men, then what is the ratio between the average age of a man and that of a woman, respectively?Solution
ATQ,
Total age of all men = 20 × 36 = 720 years
So, total age of all women = 720 × 0.80 = 576 years
So, average age of a woman = 576 ÷ 16 = 36 years
Required ratio = 36:36 = 1:1
