A) 45 : 56
B) 45 : 51
C) 47 : 56
D) 47 : 51
Correct Answer: A
Solution :
[a] Let the CP be Rs..\[100.\] \[\therefore \]SP=Rs.\[112\] If the marked price be Rs. x, then \[90%ofx=112\] \[\Rightarrow x=\frac{112\times 100}{90}=Rs.\,\,\frac{1120}{9}\] .'. Required ratio \[=100:\frac{1120}{9}\] \[=900:1120=45:56\] Shortcut Method Marked Price = Cost price \[\times \frac{100+\Pr ofit%}{100-\,Discount%}\] Required ratio = Cost price: Cost price\[\times \frac{112}{90}\] \[=90:112=45:56\]0You need to login to perform this action.
