Question

The cost of 11 pencils is equal to the selling price of 10 pencils. Which of the below statement is correct, whatever may be the cost of 1 pencil.

• A. 7% profit
• B. 10% profit
• C. 12% loss
• D. 7% loss

Answer 1

The correct option is B

10% profit

The cost price of 11 pencils = S.P of 10 pencils
Let C.P of 1 pencil is 1 rupee
C.P of 10 pencils = 10 rupees
S.P of 10 pencils = C.P of 11 pencils = 11 rupees
Profit on 10 pencils = 11 – 10 = 1 rupee
Profit % =$\frac{1}{10}$ $\times$ 100 = 10 %
