Thank you for using the timer!
We noticed you are actually not timing your practice. Click the START button first next time you use the timer.
There are many benefits to timing your practice, including:
The figure with + sign in the diagonal cell indicates the following:
x + 4 = 1, or x = -3 x + e = 7, or e = 10 y + 4 = -5, or y = -9 y + e = n, or n = 1 e + z = 10, or z = 0 z + 4 = m, or m = 4
Hence, m + n = 5.
+ for this, how did you figured this one? Have you came across such type of questions?
This was the first question in one of my GMATPrep tests. I kept staring at it for couple of minutes but then also understood that since this was the first question, difficulty level would be simple to medium. Finally, it was + sign in the leftmost diagonal end that gave the clue.
