Question
A person purchased diesel at Rs. 4, Rs. 10 and Rs. 15
per litre in three successive years. If he spent Rs. 4800 each year on diesel, then find the approximate average cost (per litre) paid by him in the given three successive years.Solution
According to the question, Quantity of diesel purchased by him in 1 year = (4800/4) = 1200 litres Quantity of oil purchased in 2 year = (4800/10) = 480 litres Quantity of diesel purchased in 3 year = (4800/15) = 320 litres Total quantity of oil purchased in give three years = 1200 + 480 + 320 = 2000 litres Total amount spent on diesel in given three years = 4800 × 3 = Rs. 14400 Required average = 14400/2000 = 7.2 ~ Rs. 7.2
