Question

120 men had provisions for 200 days. After 5 days, 30 men died due to an
epidemic. The remaining food will last for ______.
​

Answer 1

Answer:

In 5 days the provision consumed by 120 men = 120*5 = 600 man-days. Remaining provisions = 24000 - 600 = 23400 man-days. Men remaining after 5 days = 120 - 30 = 90 men. The remaining provisions will last the 90 another 23400 man-days/ 90 men = 260 days.

Answer 2

Answer:

260 days

Step-by-step explanation:

Let the amount of food 1 man eat in 1 day be equal to x. Then,

Total food = 120 × 200 × x = 24000x

Food ate in 5 days = 120 × 5 × x = 600x

Remaining Food = 24000x - 600x = 23400x

No. of Men remain after 5 days = 120 - 30 = 90

The remain food will last = 23400/90 = 260 days
