A man sells an article at a gain of 15%. If he had bought it at 10% less and sold it for Rs. 4 less, he would have gained 25%. The C.P. of the article is?
Correct Answer: Rs. 160
Explanation:
∵ (115% of C.P.) - (125% of 90% of C.P.) = 4
⇒ [115/100 - (125 x 90) / (100 x 100)] x CP = 4
∴ C.P. = Rs. 160
