144 pints  because if she has a 20 gallon tank that's 160 pints she took out 3 gallons which would be 24 pints 160-24=136. then she put back in 2 quarts which is 4 pints which is 136+4= 140 the each fish has 1 pint of water so 140+4=144

  Amount of the water in the aquarium is 144 pints.

Water filled in aquarium with water initially = 20 gallons

Since, 1 gallon = 8 pints

Therefore, water in aquarium = 8 × 20

                                                 = 160 pints

Water taken out from the aquarium = 3 gallons Or 24 pints

Water in the aquarium = 160 - 24 = 136 pints

Rhonda added water back in the aquarium = 2 quarts

Since, 1 quarts = 2 pints

Therefore, 2 quarts = 4 pints

Now water in aquarium = 136 + 4 = 140 pints

She added 4 fish having 1 pint of water with each fish.

Therefore, by adding 4 fish in the aquarium, water added = 4 pints

Now the amount of water in the aquarium = 140 + 4 = 144 pints

  Therefore, there are 144 pints water in the aquarium.
