90 persons consume 810kg of food in 27 days. In how many days will 60 persons consume 300kg of food?

Correct option is C

Step 1: Calculate the daily consumption per person in the first scenario. Given: 90 persons consume 810 kg of food in 27 days. Daily consumption per person: Daily consumption per person = 810 / (90 x 27) = 0.3333 kg/day Step 2: Calculate the number of days for 60 persons to consume 300 kg of food. For 60 persons consuming 300 kg of food, we use the equation: Total consumption for 60 persons in d days = 60 x d x 0.3333 = 300 Solving for d: d = 300 / (60 x 0.3333) = 300 / 20 = 15 days Thus, 60 persons will consume 300 kg of food in 15 days.
