xy > 3x – xy
or x(2y-3)>0
therefore x>0 or y>1.5
or x<0 or y<1.5

St 1: y>1.5. therefor y>1. ANSWER
St 2: x>0. condition 1 applies. therefore y>1.5 or y>1. ANSWER

1) the question asked if is y > 1?, the statement says y > 1.5. No need to work out anything
1 is sufficient

2) 2 is also sufficient. If x is a number greater than 0, then y will always be 1.5

Dear Moderator ,

Is this question , as it is supposed to be . The statement itself gives the answer.

Edit :

My Bad question is perfect. Did not realize that x<0 and y <1.5 can also be a solution .

If xy > 3x – xy, is y > 1?
\(xy>3x-xy........2xy>3x........2xy-3x>0.........x(2y-3)>0\)
so two case-
a) x>0, so \(2y-3>0.......2y>3.......y>\frac{3}{2}\)
b) x<0, so \(2y-3<0.......2y<3.......y<\frac{3}{2}\)

(1) y > 1.5
clearly y>1
sufficient

(2) x > 0
see case (a), if x>0, \(y>\frac{3}{2}\)
sufficient

D
