What are the values of p and q ?
I p and q are positive integers such that `(p+q)/(2) lt 2p and pq=30`
II p and q are Integers that differ by 1 and pq=30

Options

A. If the question can be answered using one of the statements alone, but cannot be answered using the other statement alone.
B. If the question can be answered using either statement alone.
C. If the questions can be answered using I and II together but not using I or II alone
D. If the question cannot be answered even using I and II together.

Answer

D

Explanation

From statement I, we have `(p+q)/(2) lt 2p rArr q lt 3p and p,q=30` which implies (30,1), (15,2), (6,5) and (5,6) all are possible values of p,q. Hence we cannot find unique value of p and q.
Statement II alone is also not sufficient as p and q may be possitive or negative.
Thus the uniqe values of p,q cannot be found.
