Question 1065716
In a group of people the ratio of the number of women to the number of men is 11:9.
 The average age of the women is 22, and the average age of the men is 32.
 What is the average age of the whole group?
:
For the purpose of this problem we can assume the no. of women is 11, the no. of men is 9 and there are 20 people altogether
:
A = {{{(11(22) + 9(32))/20}}}
A = {{{(242+288)/20}}}
A = {{{530/20}}}
A = 26.5 yrs is the average age of the group
