Distance of new office of Dharmesh is 14.28% less than the previous office, still his expenditure on petrol increased by 20%. What is the increase in the price of petrol?
Sol Expenditure is directly proportional to distance and also directly proportional to petrol price E= DP New expenditure is 120% = 6/5, New distance is 14.28% less means 1/7 less = 6/7 So (6/5)E = (6/7)D (P’) (6/5)DP = (6/7)D P’ So P’ = 7/5P = 1.4 P = 140% P Hence increase in price of petrol is 40%
