Answer:

Correct Answer: A

Solution:

Let their CP be $ Rs\text{. }x $ and $ Rs\text{. (900}-x), $ respectively. Then, $ \frac{120}{100}\times x+\frac{75}{100}(900-x)=900 $ $ \frac{45x}{100}=225 $
$ \Rightarrow $ $ x=( \frac{225\times 100}{45} )=500 $

$ \therefore $ Required $ CP=900-x $
$ \Rightarrow $ $ 900-500=400 $
