Question

A family of 8 people have enough stock of rice to last for 30 days. Due to arrival of some friends, this food was consumed in 20 days. How many friends join the family?​

Answer 1

Answer:

No of People and no of days food stock lasting are Inversely proportional

Here, 240 people can consume in 1 day

or, 1 people can consume in 240 days= 20*12 days

or, 12 people can consume in 20 days

or (8+4) people can consume in 20 days

So, addition of 4 people can consume in 20 days
