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?

If the question stem didnâ€™t ask for â€œat leastâ€ Manager Joined: 25 Oct 2004 Posts: 247 ### Show Tags 31 Mar 2005, 12:04 Dont have the OE but the OA is E SVP Joined: 03 Jan 2005 Posts: 2233 ### Show Tags 31 Mar 2005, 12:37 Explanation for choose E might be because "average sales" is undefined in the question. 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.

- $60000/30 or -$60000/29 or
- \$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.
