In a family of 8, the men eat on average 72kg of food and women eat on an average 50kg of food. The men and women are equal in number. A hungry woman named rekha joined the family for dinner and the average consumption became 67.How much did rekha eat (in kgs)?

As men and women are equal so, there are 4 women and 4 men so, total consumption will be
72 times;4 = 288(by men) and 50×4 = 200(by women)
Total consumption = 488.
But after including Neetu 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
