Answer 1

Take the list prize as x.
Selling Price =17100
Discount=5%
Atq;
x-5*x/100=17100
(100x-5x)/100=17100
95x=17100*100
x=17100/95*100
x=18152.63rupees

Answer 2

the selling price is 17100and the shopkeeper gave 5%discount this means that the selling price is less than the listing price.and the difference between the listing price and selling price will be 5%of listing price .so you cannot subtract 5%of 17100 from 17100because the discount is not on listing price but on selling price.thus you need to take listing price as x so you have to subtract 5%of x from 17100:-
$x- (x \times \frac{5}{100} ) = 17100$
by this you will get the value of x
If once you got x(listing price).take out the 5%of x and subtract it from17100
$17100 - (x \times \frac{5}{100} )$
