Question

The marked price of the book is Rs 225.If the shopkeeper allows a 12% discount to his customers and gains 25%,find the cost price of the book.​

Answer 1

Answer:

Rs 158.4

Step-by-step explanation:

MP = 225

Discount = 12%

Discount = (12/100)*225 = 27

Selling price = MRP - Discount

225 - 27 = 198

Gain = 25%

Gain = (25/100)*C = 0.25C

Selling price = Cost price + Gain

Selling price = C + 0.25C = 1.25C

1.25C = 198

C = 198/1.25

C = 158.4
