Is xy > x/y
2) xy >1
Statement (1) ALONE is sufficient, but Statement (2) ALONE is not
Statement (2) ALONE is sufficient, but Statement (1) ALONE is not
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is
EACH statement ALONE is sufficient
Statements (1) and (2) TOGETHER are NOT sufficient
Shouldn't the answer be B and not C ?
If xy> 1 ; then either x or y can't be 0, x or y can't be -ve. x & y can only be both negative or both are positive then xy > x/y. So B shpuld be sufficient
A alone is not sufficient as we don't know whether x is 0 or not.
B alone is not sufficient as we don't know if x>1 and 0<y<1 or x and y > 1
say x=4, y=0.5, xy=2>1, but x/y=8 xy<x/y
if x=4 and y=2, then xy=8, x/y=2 xy>x/y
A and B together, we know that x is not 0 and 0<y<1, is xy>x/y can definitely be answered.
hope this helps
