Question

In a school's hostel mess, 20 children consume a certain quantity of ration in 6 days. However,5 children did not return to the hostel after holidays.How long will the same amount of ration last now​?

Answer 1

Answer:

Total number of children = 20

20 children consume a certain quantity of ration in = 6 days

1 children consume a certain quantity of ration in = 6 x 20 days

As 5 children did not return to the hostel after holidays.

Then number of children in hostel = 20-5 = 15

Hence, 15 children consume certain quantity 6×20

of ration in = \frac { 6 x 20 }{ 15 } days = 8 days
