90 persons consume 810 kg of food in 27 days. In how many days will 60 persons consume 300 kg of food?
A12 days
B13 days
C15 days ✓ Correct
D18 days
Correct answer: (C) 15 days — The 60 persons will consume 300 kg in 15 days, so that is the answer.
Explanation
★The 60 persons will consume 300 kg in 15 days, so that is the answer.
★For 90 persons, 810 kg over 27 days means each person eats 810 over 90 times 27 per day.
★That is one third of a kg per person per day.
★So 60 persons eat 60 times one third, which is 20 kg per day.
★The days needed for 300 kg are 300 divided by 20.
★That gives 15 days.
