Let the C.P be Rs x S.P = (x × 75)/100 = Rs 3x/4 Then, New C.P = (x × 80)/100 = Rs 4/5 x New S.P = Rs (4 x)/5 × 120/100 = Rs 24/25 x According to question, 3x/4 + 63 = 24/25 x 21/100 x = 63 ∴ x = (63 ×100)/21 = Rs 300 C.P of an article = Rs 300 S.P of an article = Rs 320 Profit % = [(320 - 300)/300] ×100 = 6(2/3)%
