Answer: 11 consignmen
Explanation:
Given that a consignment of fodder can feed 1000 sheep 20 days. Assuming that all the sheep consume
fodder at the same rate, then
1000 × 20 = 20000 for 1 consignment
to feed 550 sheep for 400 days, that is
550 × 400 = 220000
The consignment that will be needed will be
220000 / 20000 = 11
Therefore, 11 consignment fodder are needed to feed 550 sheep for 400 days.
