Question 1 - Page 17 Shambhavi owns a stationery shop. She procures 200 page notebooks at ₹36 per book. She sells them with a profit margin of 20%. Find the selling price.Given Cost Price = ₹ 36 Profit margin = Profit Percentage = 20% We need to find Selling Price Now, Profit Percentage = 𝑷𝒓𝒐𝒇𝒊𝒕/(𝑪𝒐𝒔𝒕 𝑷𝒓𝒊𝒄𝒆) × 100 Profit Percentage = (𝑆𝑒𝑙𝑙𝑖𝑛𝑔 𝑃𝑟𝑖𝑐𝑒 − 𝐶𝑜𝑠𝑡 𝑃𝑟𝑖𝑐𝑒)/(𝐶𝑜𝑠𝑡 𝑃𝑟𝑖𝑐𝑒) × 100 Putting values 20 = (𝑺𝒆𝒍𝒍𝒊𝒏𝒈 𝑷𝒓𝒊𝒄𝒆 − 𝟑𝟔)/𝟑𝟔 × 100 20 = (Selling Price – 36) × 100/36 20 × 36/100 = Selling Price – 36 Selling Price – 36 = 20 × 𝟑𝟔/𝟏𝟎𝟎 Selling Price – 36 = 36/5 Selling Price – 36 = 7.2 Selling Price = 7.2 + 36 Selling Price = 43.2 Thus, selling price is ₹ 43.2
