Question

if the 80 people had eaten 100 kg rice in 20 days then 40 people eat 15 kg rice in how many days ?

Answer 1

If 80 people eat 100 kg of food in 20 days
Then in 1 day = 100/80 = 1.25 of the food is eaten.
In 20 days = 1.25 / 20 = 0.0625 of the food is eaten per day
Hence
40 people eating on 15 kg of food implies
15 / 40 = 0.375 of the food per day.
So 0.375 * x days = 0.0625
x = 6 days.
Hence 6 days is the answer.
