There are 300 men in a group. They have food for 30 days. After 10 days, 100 more men join the group. The remaining food will last how many days?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 15 days.
There are 300 men in a group and They have food for 30 days.
So, the total food = 300 × 30 = 9000
Their 10 days food = 300 × 10 = 3000
Remaining food = 9000 - 3000 = 6000
After 10 days, 100 more men join the group
So, The remaining food will last how many days = 6000/(300 + 100) = 15 days
