Hi All,
This question can be solved by TESTing THE ANSWERS.
We're told that the product of 2 positive integers is 720. Next, we're told that If one of the numbers is increased by 10 and the other reduced by 1, the product remains the SAME. We're asked for the value of the smaller of the two integers.
Since the number 7 does NOT divide evenly into 720, Answer B CANNOT be correct. So...
Let's TEST Answer D: 9
IF....
Smaller number = 9
Larger number = 720/9 = 80
Decreasing the smaller number = 9-1 = 8
Increasing the larger number = 80+10 = 90
(8)(90) = 720
This is an exact MATCH for what we were told, so this MUST be the answer.
Final Answer:
GMAT assassins aren't born, they're made,
