A man bought 9 pens for a rupee. How many pens should he sell for a rupee to gain 50%?

Let’s solve the problem step by step:

- Cost Price (CP) of 9 pens = 1 rupee, so CP of 1 pen = 1/9 rupee.

- Let the man sells x pens for 1 rupee.

- Selling Price (SP) of 1 pen = 1/x rupee.

- He wants to gain 50%. So, SP should be 50% more than CP.

- For 1 pen: SP = CP + 50% of CP = (1/9) + (1/2)*(1/9) = (1/9) + (1/18) = (3/18) = 1/6 rupee.

So, 1 pen is sold for 1/6 rupee. Therefore, x pens for 1 rupee ? 1/x = 1/6 ? x = 6.

- Option 2: 6 pens Correct answer is Option 2: 6
