ATQ, Selling price of Jackets by Shopkeeper = 0.8 × (a + 300) = Rs. 0.8(a + 300) Selling price of T-Shirt by Shopkeeper = 0.75 × (b + 400) = Rs. 0.75(b + 400) According to question, 0.8(a + 300) + 0.75(b + 400) = 1635 0.8a + 240 + 0.75b + 300 = 1635 0.8a + 0.75b = 1095 -------- (i) Also, (a + b)/2 = 700 (a + b) = 1400 -------- (ii) Solving equation (i), and (ii), we get, a = 900 and b = 500 Therefore, marked price of Jackets = 900 + 300 = Rs. 1200 And, marked price of T-shirt = 500 + 400 = Rs. 900 Cost price of Jackets = 1200/1.2 = Rs.1000 Cost price of T-shirt = 900/1.2 = Rs.750 Total cost price = Rs.1750 Selling price of jackets = 1200 × 0.6 = Rs.720 Selling price of T-shirt = 900 × 0.5 = Rs.450 Total selling price = Rs.1170 Loss percentage = (1750 – 1170) × 100/1170 = 33.14%
