After selling 72 articles, the loss equal to selling price of 9 articles. Find the Loss %.

\(11\frac{1 }{9}\)% \(12\frac{2 }{7}\)% \(14\frac{2 }{7}\)% \(15\frac{1 }{5}\)%

\(11\frac{1 }{9}\)%

ATQ,         72C - 72S = 9S                  72C = 81S                    8C = 9S                      C = 9                      S = 8    Loss % = \(\frac{1}{9}\) × 100 = 11\(\frac{1}{9}\)%
