Question

In a camp, 95 men had provisions for 200 days. After 5 days 30 men left the camp. For how many days will the remaining food last now?

Answer 1

if we consider 1 man with 1 provision for 1 Day then it makes 95 men * 1 provision * 200 days so it totals 19000 of total provision

now eliminating 5 dayz provision so 95*5 totals 475

so 19000-475 = 18525 of total provision left over

now 30 men leaves so 95-30 = 65 men left

so total days the food would last is 18525/65 = 285days.
