A merchant of clothes purchases the cloth with a gauge of 120 cm instead of 100cm. and sells it with a gauge of 80 cm with a discount of 20% . then total gain will be....
a) 10%
b) 20%
c) 25%
d) none of these
ramesh    The answer is 20%

consider he gets 120 cm for the price of 100

but sells 80 cm for the price of 100 and then offers a discount of 20%

so he sells 80 cm for the price of 80

selling price of 80 cm = 80
cost price of 80 cm =(80/120)*100=(200/3)
Gain% = ((S.P-C.P)/C.P)*100 = 20%
