Question

A computer company gives a discount of 10 % on a new piece of software. If it makes a profit of 7%, what percent does the marked price exceed the cost price?

Answer 1

say a product is $X
10% disc, that is they are selling it for $X * 90%
even if the sell for $X * 90%, they are making 7% profit, i.e $X * 90% * 7%
that means, their cost was only($X)- ( $X * 90% * 7%)
but they marked it $X

marked price exceed the cost price by....marked - cost price
= $X - (($X)- ( $X * 90% * 7%))
= $X * 90% * 7% for $x
all we need to find out how much is that for $100
