Three taps have been installed to fill a container with water. Tap A and Tap B together will take 3 hours to fill the container completely. Tap C and Tap B
together will take 4 hours to fill the same container completely. Tap A and Tap C
together will take 6 hours to fill the same container completely. How long will it
take for the three taps together to fill the container completely?​

1/A+1/B =1/3,  
1/B+1/C =1/4,  
1/A+1/C  =1/6, solve for A, B, C 
A =8 hours,  B =24/5 hours,  C = 24 hours
1/8 + 5/24 +1/24 =1/C, solve for C
C = 8/3 =2 2/3 hours - for 3 taps to fill the container.
