Two pipes A and B can fill a tank in 60 minutes. If pipe A alone can fill it in 75 minutes. How much time will the pipe B take to fill the tank alone?
Answer & explanation
Correct answer: option 2
The above chart was obtained after following the details of the question:
Efficiency of A + B = 5
Efficiency of A = 4
Efficiency of B = 5 - 4 = 1
Days required by B alone to complete the work = \(\frac{300 }{1 }\) = 300 minutes
