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
45 : 56
45 : 51
47 : 56
47 : 51
Let the CP be Rs. 100
SP = Rs 112
If the marked price be Rs. x, then 90% of x = 112
=> x = 112*100/90 = Rs. 1120/9
= 900 : 1120 = 45 : 56
