Find the unknowns x, y and z.

Name of the item Marked Price Selling Price Discount
LED TV y ₹ 11970 5%
Sum
Advertisements

Solution

LED TV selling price = 11970 discount = 5%, Marked price = y

∴ Selling price = `"Marked price" xx (((100 - "d"%))/100)`

∴ 11970 = `y xx ((100 - 5))/100`

∴ y = `(11970 xx 100)/95`

= 126 × 100

= ₹ 12,600
