AI explanation

The marked price of 150 with a 10 percent discount gives a selling price of 135. Because the shopkeeper gives a ball costing 20 free, the effective selling price for the hockey stick is 135 minus 20, which is 115. Using the profit formula where Selling Price equals Cost Price plus Profit, 115 equals Cost Price plus 15 percent of Cost Price, meaning Cost Price is 115 divided by 1.15. The cost price of the hockey is 100.
