C means that both A and B are not sufficient to answer the question right? And this is just because no information was given about what they did in June right?

Merging similar topics.

The data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether—

A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
C. BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
D. EACH statement ALONE is sufficient to answer the question asked.
E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

Solution for this problem is here: in-june-1989-what-was-the-ratio-of-the-number-of-sales-50701.html#p758992

Hope it's clear.

In June 1989, what was the ratio of the number of sales transactions made by Salesperson X to the number of sales transactions made by Salesperson Y ?

(1) In June 1989, Salesperson X made 50 percent more sales transactions than Salesperson Y did in May 1989.
(2) In June 1989, Salesperson Y made 25 percent more sales transactions than in May 1989.
Hi IanStewart
In statement 2, it seems that ''transaction'' is compared with ''year'. Shouldn't it be something like bellow?
(2) In June 1989, Salesperson Y made 25 percent more sales transactions than did in May 1989

The sentence is comparing what happened *in* June with what happened *in* May. If you deleted the second "in" from the sentence, only then would it be comparing transactions with a month of the year. Your suggested edit is not correct because "did" has no subject, but it would be correct if you included the subject:

In June 1989, Salesperson Y made 25 percent more sales transactions than she did in May 1989

But the original is fine too -- we often omit words in English comparisons when the meaning is clear.

What am I doing wrong here?

Statement 1: NS
Statement 2: NS

Combining both

Scenario 1: Sales Transactions in May for Y 100, Sales Transactions in June for X 150, Sales Transactions in June for Y 125. Ratio= 150/125=6/5
Scenario 2: Sales Transactions in May for Y 8, Sales Transactions in June for X 12, Sales Transactions in June for Y 9. Ratio= 12/9=4/3


Hence E

You broke the 25 percent rule.

If Y_May = 8, Y_June must be 8 * 1.25 = 10, not 9.
