Question
A container can hold 1,000 liters of liquid. If it is
filled with 30% water and 70% oil, how many liters of oil are in the container? If 50 liters of oil is drained from the container, what percentage of the remaining liquid is oil?Solution
Oil in the container = 70% of 1000 = 700 liters. Remaining oil after draining = 700 - 50 = 650 liters. Remaining liquid = 1000 - 50 = 950 liters. Percentage of oil in remaining liquid = (650 / 950) * 100Â ~ 68.4%.
