Answer 2

Concept:

The price at which a good or service can currently be purchased or sold is known as the market price. The dynamics of supply and demand influence the market price of a good or service. The market price is the cost at which the quantity supplied and the amount demanded are equal.

Given information:

Selling Price of an article = Rs $192$

First discount = $20$%

Marked price of an article= Rs$400$

Second discount on the article = $x$%

To find:

Second discount on the article needs to be find out.

Solution:

Selling Price of an article = Rs $192$

First discount = $20$%

Marked price of an article= Rs$400$

Second discount on the article = $x$%

Now,

Selling price after first discount = Marked price * ($100$ - first discount%)/$100$

                                                     = $400*(\frac{100-20}{100} )$

                                                     =$400*(\frac{80}{100} )$

                                                     =Rs$320$

Selling price after second discount = Marked price * ($100$ - second               discount%)/$100$ = $320*(\frac{100-x}{100} )$

Selling Price of an article = Rs $192$

Now,

$320*(\frac{100-x}{100} )$ =   $192$

$320*(100-x)=19200\\100-x=60\\x=40$

Second discount on the article is $40$%
