Question 20

Foodgrains for 220 soldiers have been stored in a fort. Foodgrains will be consumed in 16 weeks, if each soldier is given 45 gm per day. The same foodgrains will last for 24 weeks if each soldier is given 33 gms per day and some soldiers are removed. How many soldiers should be removed ?

Solution

Share

220 soldiers - 16 weeks - 45  gm/day

x soldiers - 24 weeks - 33 gm/day

So, x = 220 x 16/24 x 45/33

= 200 soldiers.

Number of soldiers removed = 220 - 200 = 20
