3/4 part of tank is full of water. When 30 litres of water is taken out it becomes empty.The capacity of the tank is?Options30 litres40 litres50 litres60 litres

The problem states that 3/4 of the tank's capacity is equal to 30 litres, because when this amount is removed, the tank becomes empty.

To find the full capacity of the tank, we need to calculate what 1 whole (or 4/4) would be.

Step 1: If 3/4 is equal to 30 litres, then 1/4 (which is one part of the tank) is equal to 30 litres divided by 3, which is 10 litres.

Step 2: Therefore, the full capacity of the tank (4/4) is equal to 4 parts times 10 litres, which is 40 litres.

So, the capacity of the tank is 40 litres.

The problem states that 3/4 of the tank's capacity is equal to 30 litres, because when this amount is removed, the tank becomes empty.

To find the full capacity of the tank, we need to calculate what 1 whole (or 4/4) would be.

If 3/4 is equal to 30 litres, then 1/4 (which is the tank's capacity divided by 4) would be 30 litres divided by 3, which equals 10 litres.

Therefore, the full capacity of the tank (or 4/4) would be 10 litres times 4, which equals 40 litres.

So, the capacity of the tank is 40 litres.
