The ratio of the prices of three different types of cars is 4:5:7. If the difference between the costliest and the cheapest cars is Rs. 60000 the price of the car of modest price is:
Correct answer: B. Rs. 100000
- A. Rs. 80000
- B. Rs. 100000
- C. Rs. 140000
- D. Rs. 120000
Explanation
The price difference between the costliest and cheapest cars is 7 - 4 = 3 ratio parts, so 3 parts = Rs. 60,000 and 1 part = Rs. 20,000. The moderately priced car has 5 parts, so its price is 5 x Rs. 20,000 = Rs. 100,000; the likely wrong choice is Rs. 80,000, which corresponds to 4 parts and the cheapest car.
