1. Madhav spent ?1200 on buying 6 stools. One ofstools was sold at a loss of 10% by mistake. Ataprice should the remaining five stools be sold son4%. Find thethe net gain is 8%?​

In the case where loss and gain percentage is common on the sameselling price always a loss incurs in total deal and this can be calulated by a short cut

Loss on total deal

=(Common loss or gain percentage 10)2=(2010)2=4%

alternatively it can be also calculated through Graphic Change Method: this can be given by

100=20% gain ----> 120= 20% LOSS ---> 96

loss = 4% (as 100 became 96)

hope it helps you
