Show Answer

Answer:

Correct Answer: A

Solution:

Let the CP of pair of sunglasses be Rs. $ x, $ then $ SP=x+25 $ % of $ x=\frac{5}{4}x $ $ x-25 $ % of $ x+40 $ % of $ (x-25 $ % $ ofx)=\frac{5}{4}x-10 $

$ \Rightarrow $ $ \frac{3x}{4}+\frac{2}{5}\times \frac{3x}{4}=\frac{5}{4}x-10 $

$ \Rightarrow $ $ 15x+6x-25x=-200 $

$ \therefore $ $ x=50 $ CP of pair of sunglasses = Rs. 50
