(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.
What is (June X)/(June Y)?

Statement 1: In June 1989, Salesperson X made 50 percent more sales transactions than Salesperson Y did in May 1989.
(June X)/(May Y) = 150/100 = 3/2.
INSUFFICIENT.

Statement 2: In June 1989, Salesperson Y made 25 percent more sales transactions than in May 1989.
(June Y)/(May Y) = 125/100 = 5/4.
INSUFFICIENT.

Statements combined:
Ratios can be MULTIPLIED:
(June X)/(June Y) = (June X)/(May Y) * (May Y)/(June Y) = 3/2 * 4/5 = 6/5.
SUFFICIENT.

The correct answer is C.
