Question
A shopkeeper allows 20% discount on his advertised price
and to make a profit of 25% on his outlay. What is the advertised price (in Rs.) on which he gains Rs.6000?Solution
let MP(marked price) = Rs 100 discount = 20% of MP = Rs 20 Selling price (SP) = Rs 80 SP = 125% of CP = (125/100) × CP 80 = (125/100) × CP CP = (125/100) × 80 CP = Rs 64 gain = 80 – 64 = Rs 16 now real gain = 6000 16 = 6000 1 = 375 MP = Rs 100 = 100 × 375 = 37500
