Instruction for question 15 to 20:
Ravi works in an online food-delivery company. After each delivery, customers rate Ravi on each of
four parameters - Behaviour, Packaging, Hygiene, and Timeliness, on a scale from 1 to 9. If the total
of the four rating points is 25 or more, then Ravi gets a bonus of 20 for that delivery. Additionally, a
customer may or may not give Ravi a tip. If the customer gives a tip, it is either 30 or 50.
One day, Ravi made four deliveries - one to each of Atal, Bihari, Chirag, and Deepak, and received a
total of 120 in bonus and tips. He did not get both a bonus and a tip from the same customer.
The following additional facts are also known.
1.
In Timeliness, Ravi received a total of 21 points, and three of the customers gave him the
same rating points in this parameter. Atal gave higher rating points than Bihari and Chirag in
this parameter.
2. Ravi received distinct rating points in Packaging from the four customers adding up to 29
points. Similarly, Ravi received distinct rating points in Hygiene from the four customers
adding up to 26 points.
3.
Chirag gave the same rating points for Packaging and Hygiene.
4. Among the four customers, Bihari gave the highest rating points in Packaging, and Chirag
gave the highest rating points in Hygiene.
5. Everyone rated Ravi between 5 and 7 in Behaviour. Unique maximum and minimum ratings
in this parameter were given by Atal and Deepak respectively.
6. If the customers are ranked based on ratings given by them in individual parameters, then
Atal's rank based on Packaging is the same as that based on Hygiene. This is also true for
Deepak.
Q. 15)
