Directions (Q. 6-10): In each of the following questions two equations are given. You have to solve them and give answer as:

1) if p < q

2) if p > q

3) if p ≤q

4) if p≥q

5) if p = q or no relation can be established

6. I. 2p^{2}- 7p + 3 = 0

II. 4q^{2 }+ 3q - 1= 0

7. I. p^{2}- 169 = 0

II. q^{2}- 289 + 195 = 0

8. I. p^{2}- 5p + 6 = 0

II. q^{2}- 3q + 2 = 0

9. I. 4p^{2}- p - 3 = 0

II. 2q^{2}+ q - 1 = 0

10. I. p^{2}+ 11p + 30 = 0

II.q^{2}- 11q + 30 = 0
