Answer 2

Answer:

a) Let the C.P. = Rs. x

Profit =20%

Then S.P. =

100

120

×x=

5

6x

⇒

5

6x

−x=240

⇒

5

x

=240

⇒x=240×5

⇒x= Rs. 1200

Then S.P. =1200+240= Rs. 1440

b)let Marked price of an article be x

Discount on article =x−10%ofx

=x−

100

10

x

=0.9x

Therefore, selling price of the article=0.9x

Now, Gain % =

cp

sp−cp

Put the value of gain % and sp in the above equation and calculate cp.

100

8

=

cp

0.9x−cp

8cp=90x−100cp

108cp=90x

cp=

108

90x

cp=

6

5x

Therefore, cost price cp marked above marked price(mp) =

cp

mp−cp

×100

Put the valus of cp and mp in the above equation
