Ravi, who works for a food-delivery service, delivers food to four customers: Atal, Bihari, Chirag, and Deepak. After each delivery, he receives ratings on a scale of 1 to 9 on four parameters: Behaviour, Packaging, Hygiene, and Timeliness. If the total of the four ratings is 25 or more, he receives a bonus of ₹20. Alternatively, a customer may give a tip of either ₹30 or ₹50. He does not receive both a bonus and a tip from the same customer. He received a total of ₹120 in combined bonus and tips from the four customers.

The following information is also known:

1. In Timeliness, the total points given to Ravi by the four customers is 21. Three customers gave him the same rating, and Atal gave a higher rating than Bihari and Chirag.

2. In Packaging, the total points given to Ravi by the four customers is 29. All four customers gave him distinct ratings, and Bihari gave him the highest rating.

3. In Hygiene, the total points given to Ravi by the four customers is 26. All four customers gave him distinct ratings, and Chirag gave him the highest rating.

5. In Behaviour, all four customers rated him between 5 and 7 (both inclusive). Atal and Deepak gave the unique maximum and unique minimum ratings, respectively.
