Tap A is 50% more efficient than Tap
Tap A is 50% more efficient than Tap
B. Tap A can fill one-third of tank in D hours and the remaining tank can be filled by tap B in (D + 12) hours. If both taps are opened to fill the tank, but due to partial closing of valve, tap A was working with one-third of its efficiency and tap B was working with one-half of its efficiency, after few hours, they started working with their full efficiency, and remaining tank is filled by them in 8 hours, then find the number of hours for which taps didn’t work with their full efficiency?
