9 pencils for Rs 16
1 pencil costs Rs 16/9
11 pencils cost 11 * Rs 16/9 = Rs 176/9
11 pencils are sold at Rs 22 = Rs 198/9
So profit = 198/9 - 176 / 9 = Rs 22/9
profit % = (22/9) / (176/9) * 100 = 22 /176 * 100 = 12.5 %
1 pencil costs Rs 16/9
11 pencils cost 11 * Rs 16/9 = Rs 176/9
11 pencils are sold at Rs 22 = Rs 198/9
So profit = 198/9 - 176 / 9 = Rs 22/9
profit % = (22/9) / (176/9) * 100 = 22 /176 * 100 = 12.5 %
