Concept:- The question tests the application skills of quadrilateral and triangles
            St1 :-The area of NOPR is 30.
           There is no information about the triangle that can be derived from the area of the                                                       parallelogram.(Insufficient)

           St(2):-The area of the shaded region is the area of triangle OPQ=5  
             Triangle MNR is isosceles
             =>Height drawn from vertex N to base MR divides the triangle into two congruent right triangles                & 
            each of these right triangles will have the same area as triangle OPQ.
            => Therefore, the area triangle MNR is twice as much, or 10. Statement two alone is (Sufficient).
