Answer 2

Step-by-step explanation:

Given A person allows 10% discount on a book whose marked price is Rs 40, what will be its cost price so that there is a profit of 20%

• Now Marked Price = 40
•          Discount = 10%
•                         = 40 x 10 / 100
•                          = 4
•   Selling Price = M.P – Discount
•                        = 40 - 4
•                          = 36
•     Now profit = 20%
•         Let cost price be 100
•        Selling price = C.P + Profit  
•                               = 100 + 20
•                               = 120
• If selling price is 120, cost price is 100
• If selling price is 36, cost price is 36 x 100 / 120
•                                                            = Rs 30
• Therefore the original price of the article is Rs 30
