Saboda haka, amsar ita ce 140,000. <eng> In the first 5 hours the tank losses 32000 gallons / hour x 5 hours = 160000 gallons. In the next 10 hours the tank losses 10,000 gallons / hour x 10 hours = 100000 gallons. The total amount of water loss so far is 100000 + 160000 = 260000 gallons. The total amount of water remaining in the tank is 350000 - 260000 = 90000 gallons. Once repaired, after 3 hours, the tank gains 40000 gallons / hour x 3 hours = 120000 gallons. The total amount of water in the tank after the tank is filled for 3 hours is 120000 + 90000 = 210000 gallons. The amount of water missing in the tank for it to be full is 350000 - 210000 = 140000 gallons.
Thus, the answer is 140000.
