Question

A garrison of 200 men had enough food for 70 days, 80 men went away after 10 days. How long will the remaining food last?

Answer 1

Answer:

126

Step-by-step explanation:

if half would go then food will last till 140 day or the days would be increased by 70 so

70×80/100=56 now 70+56 =126

Answer 2

Solution:

Let, the food consumption by per person per day be x

Initial amount of food = 200 *70(x) = 14000x

consumed food = 10(x) * 200 = 2000x

Remaining food = 14000x - 2000x = 12000x

Remaining men = 200 - 180 = 120

No. of days remaining food will last = 12000(x) /120(x) = 100

so, the remaining food will last for 100 days.
