Answer 1

Step-by-step explanation:

Original Profit=12%

Cost Price=C.P.

Let the Selling price be S.P.

C.P.

S.P.−C.P.

×100=12 (1)

S.P.−C.P.=

100

12C.P.

(2)

New Selling Price is S.P.+16

C.P.

S.P.+16−C.P.

×100=20

C.P.

S.P.−C.P.+16

×100=20 (3)

Substituting (2) in (3)

C.P.

100

12C.P.

+16

×100=20

C.P.

12C.P.+1600

=20

12+

C.P.

1600

=20

C.P.

1600

=20−12=8

8

1600

=200=C.P.

The C.P. of the article=200Rs
