A stock of food is enough to feed 100 persons for 15 days... How many days will the food last if 50 more persons are added??

Sagot :

22 and 1/2 Days long will the food last.

100 + 50 = 150 people for second ratio

100 : 15 = 150 : n

15 (150) = 2250
2250 ÷ 100 = 22.5 days or 22 days and 12 hrs.

To check, the product of the means and extremes must be equal.
100 (22.5) = 15 (150)
         2250 = 2250

Therefore, the answer to your question is 22.5 days.
