Tank Proportions | MCQs

Explanation

If 1/3 of the tank holds 80 litres, we can set up a proportion to find the total capacity of the tank:

1/3 × Total Capacity = 80 litres

To find the total capacity, we can multiply both sides by 3:

Total Capacity = 80 litres × 3

= 240 litres

Now, we can find the quantity of water that 1/2 tank holds:

1/2 × Total Capacity = 1/2 × 240 litres

= 120 litres
