Answer» $(CP\; = \;\frac{{SP}}{{1\; + \;profit\% }})$ Where, CP = cost price, SP = Selling Price For whole seller: CP = Rs. 4500 Profit = 20% Using the above formula, $(4500\; = \;\frac{{SP}}{{1\; + \;20\% }})$ ⇒ 4500 (1 + 0.20) = SP ⇒ SP = 4500 × 1.20 ∴ SP = Rs. 5400 For, Sita: CP = Rs. 5400 for 15 KG. = 5400/15 = Rs. 360 per kg In FIRST two days, she sold 5 kg each day i.e., she sold 10 kg. For 10 kg, CP = Rs. 3600, profit = 25% SP = CP (1 + profit %) = 3600(1 + 0.25) = Rs. 4500 Third day, she sold 5 kg at 15 % loss. CP = Rs. (360 × 5) = Rs. 1800, loss = 15% SP = CP (1 − loss %) = 1800(1 − 0.15) = Rs. 1530 Total SP = Rs. (4500 + 1530) = Rs. 6030 Total CP = Rs. 5400 ∴ Total profit = Rs. 630 |
