Hope Porter · Answer 1

Time taken to fill the pool by faucet:

A-2 days

B-3 days

C-4 days

D-6 hours=6/24=1/4 days

Thus the time taken for the 4 faucets working together to fill the pool will be the GCD of the time taken by the 4, which will be:

GCD (2,3,4,0.25)

=1

=1 day

Answer: 1 day or 24 hours
