Combined:
We need to combine statements. Together we are solving for two numbers that add up to 16 and multiply to get 48. 12 times 4 is a solution, however, we don't know if x is 12 or 4. Thus there are two values for 1/X + 2/Y. Insufficient.

What is 1/X + 2/Y = (X+2Y)/XY ?
Stat1: X + Y = 16; we don't have value of X+2Y or XY, not sufficient.
Stat2: XY = 48; we don't have value of X+2Y, not sufficient.
Combining both, still we don't have value of X+2Y (There is no limitation of X and Y) . Not sufficient.
