Answer 2

Given: Tank is 40℅ full => 80 Litres of water

Step 1: Assume total capacity of tank = x Litres

i.e, 0.4x=80

=> x= 200 litres

Step 2: For 80% capacity

i.e, 0.8×2000

=> 160 litres

Step 3: Amount of water to be added is

=> 160-80

=> 80 litres

Hence, Total capacity of Tank is 200 litres

and amount of water added for 80% full is 80 litres
