Question

by selling a music system for Rs24700, a dealer suffered a loss of 5% For how much should he sell it to make a profit of 8%

Answer 1

it's very simple

cost price of music system= 100/(100-loss) *selling price

= 100/95*24700

=26000(cost price of music system)

now,

to gain 8%

100+profit/100*cost price

=108/100*26000= 28080

hope you get this
