Question

Indian army camp there are 320 soldier. they have sufficient food for 80 Days. if after 20 days , 20 soldiers left the camp, how many more days will the food last
​

Answer 1

Answer:64days

Step-by-step explanation:

Let per soldier uses 100 grams food per day then total quantity of food is 320 soldiers× 100 grams × 80 days= 2560000 grams.

Quantity used in 20 days = 320×100×20 = 640000 grams.

So remaining quality for 320-20= 300 soldiers = 2560000-640000= 1920000 grams.

Now per day consumption is 300 soldiers × 100 grams = 30000 grams

So number of days required to use 1920000 grams

= 1920000/30000 = 64 days
