Is xy < 0?
1). (X^3 * Y^5)/ (X*Y^2) <0
2). /X/ - /y/ < /X-Y/
Please explain your approach. I am NOT just interested in knowing the answer. Thank You
from i) x^2*y^3 < 0
so x could be +ve or -ve so insuff.
from ii) it looks like triangle inequality reversed, but it should be enough
I would go with B
because either x or y must be negative for ii inequality to hold
