Let volume of tank be V.
At the end of 2 minutes (one cycle), volume of tank filled is V/16 - V/20 = V/80.
At the end of 75 cycles, volume filled is 75V/80.
Halfway through the 76th cycle, volume filled is 75V/80 + V/16 = 80V/80 = V.
So it takes 75.5 cycles (i.e.) 151 minutes for the tank to fill up.
