A big container is 30% full with water. If 54 liters of water is added, the container becomes 3/4 full. What is the capacity of the big container?	Answers
A) 36 liters  B) 40 liters  C) 45 liters  D) 54 liters  E) 120 liters

Rationale: "a big container is 30 % full with water and after 54 liters of water is added , the container becomes 75 % full . hence these 54 liters account for 45 % of the container , which means that the capacity of it is 54 / 0.45 = 120 liters . or : if the capacity of the container is x liters then : 0.3 x + 54 = 0.75 x - - > x = 120 liters . answer : e"
