Step-by-step explanation:
Given : A swimming pool can be filled in 8hrs by 4 equal pumps.
To Find: How many such pumps required if the pool is filled 16/3hrs?
Solution:
A swimming pool can be filled in 8hrs by pumps = 4
A swimming pool can be filled in 1 hr by pumps = \frac{4}{8}84
A swimming pool can be filled in \frac{16}{3}316 hr by pumps:
= \frac{4}{8}\times\frac{16}{3}84×316
= \frac{8}{3}=2.6638=2.66
Thus 3 pumps are required
