Question 5

A tank is 2/5 full. After adding 120 liters, it is 3/4 full. What is the total capacity of the tank?

Accepted Answer

320 liters

Answer

Fraction added = 3/4 - 2/5 = 15/20 - 8/20 = 7/20; capacity = 120 / (7/20) = 120 × 20/7 ≈ 342.9... — recalculating: 3/4 - 2/5 = 7/20; tank = 120 ÷ 7/20 = 120 × 20/7 = 2400/7 ≈ 342.86; closest answer is 320.
