Question

one pipe fills a water tank three times faster than other pipe. if two pipes together can fill the empty tank in 30 minutes, than how much time will the slower pipe alone take to fill the tank ?​

Answer 1

assumed time taken by slower pipe is X minute , then faster pipe will take x/3 minutes to fill the tank. if both opened together 36 minutes would take to fill the tank..

Now, if both pipe work one day

1/x+3/x=1/36

solving the equation 144 minutes required by slower pipe alone to fill the tank.

x=144 min.
