Is x greater than y ?
(1) 3x = 4y
(2) x = k/3, y= k/4 and k > 0
(1) 3x = 4y
(2) x = k/3, y= k/4 and k > 0
Pure algebraic questions like this one are no longer part of the GMAT Data Sufficiency syllabus.

Bunuel
(1) 3x = 4y or x = 4/3 y
Now if y = 3, x = 4 (here x > y)
But if y = -3, x = -4 (here x < y)
So not sufficient.
(2) k = 3x, k = 4y. This means 3x = 4y or x = 4/3 y or x = y + y/3
Also since k > 0, x and y also both must be positive.
Clearly x > y because to get x, we need to add y/3 to y (a positive value added to another positive value)
Sufficient.
Hence B answer
