Question
A seller calculated his intended selling price at 6%
profit on the cost of a product. However, owing to some mistake while selling, the units and tens digits of the selling price got interchanged. This reduced the profit by Rs. 180 and profit percentage to 2.4%. What is the cost price of the product?Solution
Profit % reduced = 6 - 2.4 = 3.6% Therefore, required C.P = (180/3.6) x 100 = Rs 5000
