Question

a table is sold at a profit of 13%.Had it been sold for $25 more the profit would have been 18% .find it's CP​

Answer 1

Answer:

Let Cost price of table = $ y

We know that ,

S. P. at R% profit =  

(100 + R)

× C.P.

100

According to question,

∴  

113y

+ 25 =  

118y

%

100 100

⇒  

118y

-

113y

= 25

100 100

⇒  

5y

= 25 ⇒  

y

= 25

100 20

⇒ y = 25 × 20 = $ 500

We can find required answer with the help of given formula :

Here, a = 13%, and R = $ 25, b = 18%

C.P. of table =   R   × 100

b - a

C.P. of table =    

25

× 100

18 - 13

C.P. of table =  

25

× 100 = $ 500
