To find the vendor's profit or loss, we need to calculate the total cost price and the total selling price.

1. Total Cost Price (CP):
The vendor bought 10 dozen eggs at a rate of 22 rupees per dozen. Therefore, for 10 dozen eggs, the cost price would be:
CP = 10 x 22 = 220 rupees.

2. Total Selling Price (SP):
Out of the 10 dozen eggs, six of them were rotten and discarded. Therefore, the vendor sold the remaining eggs, which are 10 dozen minus 6 eggs, i.e., 114 eggs. The selling price of each egg is 2.50 rupees. Hence, the total selling price for 114 eggs would be:
SP = 114 x 2.50 = 285 rupees.

Now, we can calculate the profit or loss using the following formula:

Profit (P) = Selling Price (SP) - Cost Price (CP)

Profit = 285 - 220
Profit = 65 rupees

The vendor's profit is 65 rupees.
