Question

270 kgs of corn would feed 42 horses for 12 days for how many days would 360 kg of it
feed 21 horses

Answer 1

No: of horses is directly proportional to corn(work) and inversely proportional to days.

Hence,

42 * 21/270 = 21 * D/360

D = 42*21*360/21*270 = 56 days.

Hence it will last for 56 days.

Hope it helps.

Answer 2

56 days................
