This looks like C.

Anyone wants to try a variation?

Total revenues in Y = $40,000. [Everything else remains the same] _________________ Who says elephants can't dance?

Month X could have any of 31, 30, 28 or 29 days. Since the avegare daily sales = A, the total sales for Month X could be any of: 31X, 30X, 28X or 29X Now, month Y could have any of 31, 30, 28 or 29 days in all. Clearly, statements (1) and (2) are insufficient if treated separately, let us just examine case (C) here: For month X, total revenue from sales was$ 35,000 - (1)
AND
For month Y, total revenue fro sales was $60,000 - (2) (1) implies, the average daily sales for Month X could be -$35000/31 or
- $35000/30 or -$35000/29 or
- $35000/28 (2) average daily sales for Month Y could be -$60000/31 or
- $60000/30 or -$60000/29 or

(2) For month Y, total revenue fro sales was $60,000 I selected E you need to know the number of transactions for each month to compute the average sale value. What's the OA?

You guys added the word "daily" to make it clear, but is it the intend of the question? _________________ Keep on asking, and it will be given you; keep on seeking, and you will find; keep on knocking, and it will be opened to you.

- \$60000/28

Hence, both combined, insufficient.

Is my approach fine or am I just being paranoid?

Good explanation.

Good thinking but will this not lead to answer E, for if you calculate them out you'll see the answer is unique and C would be your answer.
