उत्तर

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 × total capacity

= `35/100 xx 200` = 70 l

70 l of water to be filled
