Rs. 62.5

Rs. 43

Rs. 43.20

Rs. 65

- When a pen is sold for Rs. 50 with a 20% loss, it means the selling price is 80% of the cost price.

- To find the cost price, denote it as 'CP.'

- We know that 80% of 'CP' = Rs. 50.

- Therefore, calculate CP:

\(\text{CP} = \frac{50 \times 100}{80} = Rs. 62.5\)

- Explanation of Options:

- Option 1: Rs. 64.40 - This value is not 80% of Rs. 50.

- Option 2: Rs. 62.5 - This is 100% correct as calculations show.

- Option 3: Rs. 43 - This is below Rs. 50, certainly incorrect.

- Option 4: Rs. 43.20 - Incorrect for similar reasons as Option 3.

- Option 5: Rs. 65 - Incorrect because it's greater than Rs. 62.5.

- Correct Answer: Option 2 - Rs. 62.5
