allowing 20% discount on the marked price of a watch the value of the watch will be Rs 6328 when a vat 13%is added ,find the final price.​

Step-by-step explanation:

Let the marked price of a watch be =₹x

∴ Discount price = x- 20% of x

= x - 0.2x

=0.8x

Amount of VAT = 13% of 0.8x

0.13 x 0.8x

0.104x

Now,

Selling price = 0.8x + 0.104x

              ∴6328 = 0.904x

x = 0.904 / 6328

x=0.00014285714
