Question

A tank can hold 200 litres of water. At present, it is only 40% full. How many litres of water to fill in the tank, so that it is 75 % full?

Answer 1

Capacity of the water tank = 200 litres 

Percentage of water in the tank = 40% 

Percentage of water to fill = Upto 75%

Difference in percentage = 75 % – 40 % 

= 35 % 

∴ Volume of water to be filled = Percentage of difference x total capacity 

= \(\frac{35}{100}\) x 200 

= 70 l 

70 l of water to be filled
