Question
A container has only two types (P and Q) of oil in the
ratio 3:2 respectively. When 80 litre of oil Q is added to theĀ containerĀ the quantity of oil P becomes 25% of that of oil Q. Find the capacity of theĀ containerĀ if it becomes full after addition of 80 litre of oil. TYPE 7Solution
Let the quantity of oil in the containerĀ be 3x and 2x litres respectively. According to the question, => 3x = 0.25 Ć (2x + 80) => 2.5x = 20 => x = 8 Total capacity of the containerĀ = 3x + 2x + 80 = 120 litres.
