Question

A man purchases 9 pens for 10 rupees and sells them at the rate of 6 pens for 7 rupees. What is his profit or loss percentage?

Answer 1

Answer:

Cost price of 9 pens= 10 Rs.

Cost price of 1 pen= CP= 10/9 Rs = 1.1111 Rs.

.

Selling price of 6 pens= 7 Rs.

Selling price of 1 pen= SP= 7/6 Rs = 1.1667 Rs.

.

So, Selling price is higher than cost price for each pen. 1.1667 > 1.1111

Hence, the man obtained profit. SP > CP.

.

Profit percentage= (SP-CP)×100÷CP = (1.1667-1.1111) ×100 ÷1.1111

= 0.05555x100 /1.111

= 5.555/1.111 = 5%.

Answer 2

Step-by-step explanation:

Cp of 9 pens =10

Sp of 6 pens =7

Cp of 1 pen =10/9

Sp of 1 pen =7/6

10/9 <7/6

Sp>Cp so we got profit

P%= p/cp*100

5.555÷1.111

=5%
