Question
There are two inlet pipes 'P', 'Q' and one outlet pipe 'R' in a tank. ‘P’ and ‘Q’ can fill the tank in 20 minutes and 10 minutes respectively. ‘R’ is 50% less efficient than ‘P’. If ‘P’ and ‘R’ are open together but after 10 minutes, ‘P’ is replaced with ‘Q’, find the total time required to fill the tank completely.
