Question
What was the difference between the number of petrol
cars in perfect conditions of Hyundai & that of Ford? Read the table carefully and answer the following questions. Number of Cars manufactured by five companies and percentage of defective cars & percentage of Petrol cars out of perfect cars in 2017 Assume that there are only 2 types of car manufactured i,e. Petrol & diesel.Solution
Number of cars in perfect conditions of Hyundai = 35000 × 88/100 × 40/100 = 12320 Number of cars in perfect conditions of Ford = 30000 × 95/100 × 50/100 = 14250 Therefore, required difference = 14250 – 12320 = 1930
