Three friends want to hire a taxi for a trip. The taxi owner provides them with following three options: A. You can hire the taxi without an accompanying driver. This would cost you Rs. 2500 per day. Driver can be arranged from another agency for Rs. 500 per day. B. You can hire the taxi with driver from the first agency. This would cost you Rs. 2800 per day. But driver will have to be provided relief fund of Rs.250 per day if total distance traveled exceeds 1500 KM. C. You can hire the taxi without an accompanying driver. This would cost you Rs. 2500 per day. Driver can be arranged from another agency for 50 paise per KM. If they had planned to travel total of 6000kms in 5 days. Which option would have been better? Correct Answer B Given: travel total = 6000 kms Total days = 5 days Calculation: option A: Total cost = 2500 × 5 + 500 × 5 = Rs. 15000 option B: Now If we take the average distance everyday that will be 6000/5 ⇒ 1200 km In that case they have to pay = (2800 × 5) = Rs. 14000 But in the question, it has not mentioned how much per day they travelled But again we assume that they travelled at least 1500 km per day, Then the total distance travelled by them = (1500 × 4) km = 6000 km Which is clearly equal to the actual distance travelled by them. So, at least one day they travelled less than 1500 km So, total cost can be (2800 × 4 + 250 × 4) = Rs. 12200 Which is again less than Rs 14000 option C: Total cost = 2500 × 5 + 6000 × 50/100 = 12500 + 3000 = Rs. 15500 To travel a total of 6000 km in 5 days option B would be a better choice. Note: In the official Answer key correct answer is option B.
