Answer 2

When marked price is Right 100

Let us keep selling price as Rs 85 because when we discount we reduce the some amount in marked price and that becomes the selling price of a object.

When selling price is 680 then the marked price = 100/85 *680 (divide 100 and 85by 5th table)

=26/17*680

=26*40 (divide 17 and 680 in 17th table)

=Rs 1040.

Discount =Rs 360.
