The ratio of the times taken by tap A to fill the bathtub to that taken by tap B is 5:6. If tap A takes 36 minutes to fill a bathtub, how long would tap B take to fill the same bath tub?

Step-by-step explanation:
Tap A can fill a tank in 36 minutes which means that 1/36th of the tank will be filled up in a minute
Tap B can fill a tank in 48minutes which means that 1/48th of the tank will be filled up in a minute
and Given that A is open for 27 min --> 27/36 or 3/4 of the tank will be filled and B has to fill the remaing 1/4th of the tank.
B will fill the enitre tank in 48 mins and for it to fill 1/4 th of the tank it will take (48/4)12 mins.
hope it helps!!
