A shopkeeper earns a profit of 12% on selling a book at 10% discount on the printed price. The ratio of the cost price and the printed price of the book is
-
- 99 : 125
- 25 : 37
- 50 : 61
- 45 : 56
Correct Option: D
Let the printed price of the book be x.
| ∴ Selling price = 90% of x = x × | = | 100 | 10 |
If the CP of the book be y, then
| y × | = | 100 | 10 |
