Let the C.P be Rsx S.P = (x× 80)/100 = Rs 80/100 x Then, New C.P = (x× 90)/100 = Rs 90/100 x New S.P = Rs [(90x)/100] × [130/100] = Rs 117/100 x According to question 80/100 x + 74 = 117/100 x 37/100 x = 74 ∴x = (74 ×100)/37 = Rs 200 C.P of an article = Rs 200 S.P of an article = Rs 220 Profit % = [(220-200)/200] × 100 = 10%
