7 minutes


2000 L tank contains 550 L water and another tank contains 1600 L water. Both tank's water will be equal when 2nd tank delivers water to 1st tank.
The quantity of water will be delivered by 1st tank = #[1600+550]/2 - 550 = 525 L#.
Time taken by 2nd tank to delivers the water = 525#-:#75 = 7 minutes
