Answer:
Correct Answer: B
Solution:
- [b] Let CP of the bicycle = Rs. x
$ \therefore $ SP of the bicycle $ =\frac{110x}{100}=Rs.\frac{11x}{10} $ Now, MP of the bicycle = Rs. 1100
$ \therefore $ SP of the bicycle $ =\frac{1100\times 90}{100}=Rs.990 $
$ \therefore $ $ \frac{11x}{10}=990 $
$ \Rightarrow $ $ x=\frac{990\times 10}{11} $
$ \Rightarrow $ $ x=Rs.900 $
