30 - In parallelogram corresponding angles are equal and consecutive angles supplementary (supplementary angles are two angles that add up to 180°), thus : 
140  =  2y 	2y   +   x  =  180 
y  = 70 		 = > 140   +   x  =  180
                 = > x =  40 
Now, y  -  x  =  70 - 40  =  30 
So, the answer choice is (a) 30

In the figure above, if PQRS is a parallelogram, then y-x=?
