A tank is 3/5 full of water, a storm adds 1330 litres of water and the tank is 2/3 full. What is the total capacity of the tank

19,950 liters.

Step-by-step explanation:

Let x liters be the total capacity of the tank.

2/3x - 3/5x is equivalent to 1330 liters:

2/3 x - 3/5 x = 1330

1/15 x = 1330

x = 1330 * 15

x = 19,950.

3/5=0.6

0.6x100 = 60% (3/5 is 60% of the tank)

2/3 = 0.667

0.667x100 = 66,7 % (2/3 is 66,7 %)

66,7 - 60 = 6,7% (first was it just 60 present, after the 1330 liter water was it 66,7 present. It mean that 1330 liter is 6,7 percent.

1330/6.7 = 198,51 Liter water (every percent is 198,51 liter water)

198,51 x 100 = 19851 liter water
