Discount amount = 40% of 1500 = 0.40 × 1500 = Rs. 600.
Selling Price = Listed Price - Discount = 1500 - 600 = Rs. 900.
The shopkeeper makes a profit of 20% on the original cost of the item.
Let the original cost be denoted as C.
Selling Price = Cost + Profit.
Profit = 20% of the original cost = 0.20 × C.
Since we know the selling price is Rs. 900, we can write the equation:
900 = C + 0.20C
900 = 1.20C.
The original cost:
C = 900 / 1.20 = 750 Rs.
छूट राशि = 1500 का 40% = 0.40 × 1500 = रु. 600.
विक्रय मूल्य = सूचीबद्ध मूल्य - छूट = 1500 - 600 = रु. 900.
दुकानदार वस्तु की मूल लागत पर 20% का लाभ कमाता है।
मान लीजिए कि मूल लागत को C के रूप में दर्शाया गया है।
विक्रय मूल्य = लागत + लाभ।
लाभ = मूल लागत का 20% = 0.20 × C.
चूँकि हम जानते हैं कि विक्रय मूल्य रु. 900, हम समीकरण लिख सकते हैं:
900 = C + 0.20C
900 = 1.20C.
मूल लागत:
C = 900 / 1.20 = 750 रु.
