What was the difference between the number of petrol cars in perfect conditions of Hyundai & that of Ford?
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
