Question

an article was sold at a loss of 8% .had it been sold for rs 2500 more the gain would have been 12% find the cost price of the article
​

Answer 1

Answer:

Step-by-step explanation:

Suppose the cost price of the article is Rs.100 at the loss of 25% the S.P of the article is Rs.(100−25)=Rs.75.

At a profit of 5% the S.P of the article is Rs. (100+5)=Rs.105

∴ The difference of the two S.Ps is Rs.105−75=Rs.30

If the C.P is Rs.100,

The difference in the two S.Ps is Rs.60 then the C.P is

30

100

×60=Rs.200

(ii) Suppose the cost price of article is x

At 25% loss,

S.P =x−

At 5% profit,

S.P=x+

=60

⇒

=60

⇒x=

60×20

=200

∴ The cost price of article is Rs.200.
