Answer 1

The price at which a buyer purchases
an article is called the cost price (CP)

of the article for the
buyer.

 

The price at which a seller
sells an article is called the selling price (SP) of the article for the seller

 

When the selling price is
more than the cost price of an article then there is a profit or gain.

 

S.P>C.P

Profit= S.P – C.P

 

Profit%= (profit/C.P)×100

Profit and loss are calculated on a
certain percent of the C.P.

 ========================================================

Solution:

Given:

Cost price(CP) of each article=₹8000

Profit of 8% on TV

Loss of 4% on VCR

 

C.P of TV= ₹8000



Profit on  TV = Cost price × profit %

Profit on TV = 8%of 8000



=8000 ×(8/100)

=80×8

= ₹640

 

C.P of VCR= ₹8000


 Loss on
VCR = Cost price × Loss %

Loss on VCR= 4% of 8000



=8000 ×(4/100)

=80× 4

= ₹320


Since profit 
is more than loss,

Hence, the shopkeeper gains net profit



Net Profit= 640 -320= 320



Now

Total cost Price of both article= 8000+ 8000
=₹16000

 

Profit%= (profit/C.P)×100


 Profit %=
(320/16000) ×100

Profit % = 32/16


Profit %=2%

Hence, the gain in the whole transaction = 2%.
