Question

There is sufficient food for 500 men for 40days. After 10days, 200 men
leave the place. How many days will the rest of the food last for the rest
of the men?​

Answer 1

Answer:

This is like a time and work question

400 men x 50 days = 20000 (total food)

This is your standard equation for total food.

Now, for 20 days, 400 men will eat:

20 x 400 = 8000

Food left = 12000.

Men left = 300

300 x no. Of days = 12000

No. Of days = 12000/300

= 40
