Question

Food worth Rs 48000 lasts for 6 days in a hostel with 40 children. If the number of children were 30, how many days would the food last.​

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
