Answer 1

Step-by-step explanation:

Cost price of an article, CP= Rs 180

Profit or gain = 20 %

Discount on the marked price of an article =10%

Marked price of an article, MP=?

Let the marked priice of an article be x.

Discount on the marked price on an article =x−0.10x

=0.9x

∴ Selling Price of an article is, SP=0.9x

We know that,

CP

SP−CP

=Gain%

Put SP=0.9x, CP=180, and Gain=20 %

180

0.9x−180

=20%

180

0.9x−180

=

100

20

180

0.9x−180

=

5

1

36

0.9x−180

=1

0.9x=36+180

0.9x=216

x=

0.9

216

x=240

∴ Marked Price of an article is Rs 240.
