Question: In a family of 8, the men eat on average 72 kg of food and women eat on an average 50 kg of food. The men and women are equal in number. A hungry woman named Akhi joined the family for dinner and the average consumption became 67. How much did Akhi eat (in kgs)?
Solution:
As men and women are equal so , there are 4 women and 4 men so, total consumption will be 72 × 4 = 288(by men) and 50 × 4 = 200(by women)
Total consumption = 488.
But after including Akhi the average consumption for 9 people is given to be 67.
So the total consumption will be 67 × 9 = 603.
So, Neetu’s consumption will be = 603 - 488 = 115
