Solutions
CP for coffee = Rs. 200 and mark up % = 25%
Hence MP = 200 x 1.25 = Rs. 250
Discount = 8%
Hence SP = 250 x 0.92 = Rs. 230
So Profit = Rs. 30 and Profit % = 30/200 x 100 = 15%
Similarly, calculating for the remaining items, we get:

Discount offered on one unit of coffee = Rs. 20 and on one unit of chocolate = Rs. 12
This is in the ratio 5 : 3.
Since the total discount on each of the items is the same, the ratio of their quantities sold must be 3 : 5
Suppose, 3 packs of coffee and 5 chocolates were sold.
Total CP = (200 x 3) + (80 x 5) = Rs. 1000
Total SP = (230 x 3) + (108 x 5) = Rs. 1230
