a fruit seller bought 8 boxes of grapes at Rs.150 each. one box was damaged. he sold the remaining boxes at Rs.190 each. find the profit /loss percent.
150 * 8 = 1200 rs
1 box got damaged.........so he has 7 boxes
so hehe sold the remaining boxes at Rs.190 each
190 * 7 = 1330
profit = 1330 - 1200 = 130
% = 130 / 1200 * 100 = 65/6 %
