A shopkeeper earns a profit of 22% after selling a book at a 22% discount on printed price. Find the ratio of CP: MRP.
Answer & explanation
Correct answer: option 3
Let the printed price = 100
Discount% = \(\frac{Discount}{100}\) x 100
22 = \(\frac{D}{100}\) x 100
D = 22
SP = 100 - 22 = 78
Similarly, Profit% = \(\frac{78 - CP}{CP}\) x 100
22 = \(\frac{78 - CP}{CP}\) X 100
CP = \(\frac{7800}{122}\)
CP : MRP = \(\frac{7800}{122}\) : 100 = 78 : 122 = 39 : 61
