Civil Services Examination · Question 80

A shopkeeper employs a delivery boy and gives him a motorcycle for home delivery. For every delivery, the boy is given Rs 5. At the end of the day, he also gets Rs 2 for every kilometre of the distance covered in the day. The boy wants to earn more than Rs 500 a day, but does not want to travel more than 100 km. Which of the following numbers of deliveries would definitely meet his target?

  1. 80
  2. 85
  3. 90
  4. The question cannot be answered due to insufficient data
Show answer & explanation

Answer: (D) The question cannot be answered due to insufficient data

Explanation

Earnings = 5n + 2k, where the distance k is unknown (at most 100 km). Even 90 deliveries give Rs 450 plus an unknown distance amount, so none of the given numbers guarantees more than Rs 500.
