A man sold a bat,whose MP is 30₹, at a discount of 15% and gave a ball costing 1.50₹ free with bat & made profit of 20%. His cost of bat is?
How do we do that?
We know that the marked price of the bat is 30₹ and it was sold at a discount of 15%. Therefore, the selling price of the bat is 30₹ - (15% of 30₹) = 25.50₹.
