Question

the cost of book is rs 500 and profit is 10% find selling price​

Answer 1

Answer :

The selling price of the book is Rs. 550.

Solution :

Given,

Cost price of book = Rs. 500

Profit = 10 %

We know that,

=> S.P = C.P + 10% of C.P

$\sf\longrightarrow 500 + \dfrac{10}{100} \times 500$

$\sf\longrightarrow 500 + 50$

$\sf\longrightarrow 550$

Hence, The Selling price of the book is Rs. 550.

More information :

• Profit = S.P - C.P
• Loss = C.P - S.P
• When selling price is greater than cost price, there will be a profit.
• When cost price is greater than selling price, there will be a loss.
• P% = P/C.P × 100
• L% = L/C.P × 100

Answer 2

Given:-

Cost Price (CP) of Book = 500 Rs

Profit % = 10%

To Find :-

Selling Price (SP) = ?

Formula:-

SP = CP( 100 + P%)/100

Solution:-

SP = 500(100 + 10)/100

=> 5 × 110 = 550 Rs

Hence,

SP of books = 550 Rs
