Let the C.P of each article be Rs 100 Then, C.P of 31 articles = Rs (100 × 31) = Rs 3,100 S.P of 30 articles = Rs (3,100×135/100) = Rs 4,185 S.P of each article = 4,185/30 = Rs 139.5 If S.P is Rs 90, marked price = Rs 100 If S.P is Rs 139.5, marked price = Rs (139.5×100/90) = Rs 155 ∴ Cost price = 55/155×100 = 35.48% below Marked price
