A man sells an article at a gain 15%. If he had bought it at 10% less and sold it for 4 less, he would have gained 25%. Find the cost price of the article.	Select the correct option
A) 150 B) 160 C) 170 D) 180 E) None of these
Let the C.P. be 100   First S.P. = 115   Second C.P. = 90   Second S.P = 125% of 90 = 112.50   Difference of two selling prices is 115 – 112.50 = 2.50 and C.P. of the article is 100   But actual difference is 4.   ∴ C.P. = 100⁄2.50 × 4 = 160.   Answer 160
