Answer:
6 hours
Step-by-step explanation:
assume the total cistern is of 150 units
so one tap can fill total in 15unit/hr while second can fill total in 10 unit/hr so with together the fill 25unit/hr that means in 3 hour they filled of 75 out of 150 and remaining 75 filled by third tap in 3 hout that means it has efficiency of 25unit/hr.
That means third tap can fill whole cistern in 150/25 that means in 6 hours
mark me as brainliest :)
