Question

In the following question, read the given statement and compare Quantity I and Quantity II on its basis. (Only quantity is to be considered) (2pq + y – 4)1/4 = m2 – 3y – 1 Value of y for above equation is 20. Where p and q are roots of the equation : 2x2 – 23x + 65 = 0 Quantity I : m2 + 5 Quantity II : 2pq
