For such questions, start with your own assumptions. Since you have to calculate 2/3rd, so take up multiple of 3, let us say 300 Let us assume that the value of consignment was 300 200 sold for 5% profit = 10 100 sold for loss of 2% = -2 net result = +8 thus value of consignment = 400/8 * 300 = 15000 answer 5 DECEMBER 09 www.afterschool.tk 30 Kunal bought a suitcase with 15% discount on the labelled price.
