After 20 days; 300 men had food for 70 days
suppose 250 boys had food for x days, now less boys more days (indirect proportion)
therefore;
250 : 300 :: 70 : x
250×x=300×70
x=84days..
hope it helps..........

Hey, sis! Here is the answer.
In the camp, 300 men had food for 90 days.
50 men left after 20 days, it means that 300 men could eat (90 - 20) = 70 days more
Present number of men = 300 - 50 = 250
Hence,
300 men could eat for 70 days
1 man could eat for (300 × 70) = 21000 days
250 men can eat for
= 21000/250 days
= 84 days
Therefore, the food will last for 84 days now.
I hope that it helps you.
