Let's break down the situation step by step to determine how much each person owes you after dividing the total cost of the shopping and accounting for the contribution of the person who brought the wine.

Step 1: Total number of people

There are 10 people in total (including you).

Step 2: Total amount spent

You spent Rs 10,473 on the picnic.

Step 3: Equal share for each person

If the amount is to be divided equally among all 10 people: $\text{Equal share for each person} = \frac{10473}{10} = 1047.3 \text{ Rs}$ Each person, without any other consideration, would owe you Rs 1047.3.

Step 4: Deduction for the person who brought the wine

One person contributed a wine worth Rs 845 and wants to deduct this from their share. So, the amount that this person owes you would be: $\text{Amount owed by wine contributor} = 1047.3 - 845 = 202.3 \text{ Rs}$

Step 5: Final amounts

• The person who contributed the wine owes you Rs 202.3.
• The remaining 8 persons (excluding you and the wine contributor) owe Rs 1047.3 each.

Summary of what each person owes you:

• Wine contributor: Rs 202.3
• Other 8 persons: Rs 1047.3 each
