A merchant marked the price of an article by increasing its production cost by 40%. Now he allows 20% discount and gets a profit of Rs. 48 after selling it. The production cost is
let the production cost(PC) be Rs 100 marked price (MP) = 140% production cost {production cost = Rs 100} MP = Rs 140 discount = 20% discount = 20/100 × 140 { ∵ discount = (discount percent / 100) × MP} discount = Rs 28 selling price (SP) = Rs 112 profit = SP - PC = 112 -100 = 12 here Rs 12 is when PC = Rs 100 now when profit = Rs 48 { ∵ 12 × 4 = 48} PC = 4 × 100 = Rs 400
