Question

A shopkeeper makes a profit of 15% by selling a book for Rs 230 what is the CP and the actual profit​

Answer 1

Answer:

C.P.=₹200 & Profit=₹30

Step-by-step explanation:

Given:-

P%=15%

S.P.=₹230

Solution:-

Let the C.P. be ₹100

Now,Profit=15%of ₹100

So, Profit =₹15

S.P=C.P. + Profit

S.P=₹(100+15)

S.P=₹115

So,Now we will apply unitary method to find the cost price

When,S.P=₹115 then C.P=₹100

Now,

When,S.P=₹230,,,,then

$c.p = \frac{230}{115} \times 100$

$c.p = 200$

C.P=₹200

Now,

Profit=S.P.-C.P.

Profit=₹(230-200)

Profit=₹30
