While selling items, a shopkeeper earned a profit equal to the total cost price of items. If each item is marked up over its actual cost and a discount of is given while selling it, then what is the difference between the total cost price of items and the total selling price of items?
- Rs. 224
- Rs. 278
- Rs. 254
- Rs. 220
Answer and explanation
Correct answer: A - Rs. 224
Profit on 15 items = CP of 3, so SP of 15 = CP of 18 and SP = 1.2 CP. Also SP = 1.25 CP - 2, so 0.05 CP = 2 and CP = 40, SP = 48. 20 x 40 - 12 x 48 = 800 - 576 = 224.
