Question

Answer 1

112.5 litres

Explanation:

Here the question sats that the capacity of a water tank is 500 liters. After a downpour 3/5 of the tank is full. Then 5/8 of the water in the tank is piped to a water distilation plant. How much water is left in the tank?

Before rushing to calculate the quantity of water that is still left in the tank,we need to find the actual amount of water in the tank before some of it was pipes to a distillation plant.

3/5 × 500 = 300 litres of water

Them the amount of water that was passed on to the distillation plants plants is

5/8 × 300 = 187.5 litres of water

Therefore, the quantity of water left in the tank will be

300-187.5 = 112.5 litres

Answer 2

Amount of water left in the tank = 125 liters

Explanation:

Capacity of the tank = 500 liters

Amount of water after downpour = 2/3 × 500 = 333.33333 liters

Amount piped into a water distillation plant = 5/8 × 2/3 × 500 = 208.33333 liters

Amount of water left in the tank = 333.33333 - 208.333333 = 125 liters
