(A) 16
(B) 18
(C) 15
(D) 17

Shortcut: 51-36=15
then the overall avg
45, subtracting both avg frm overall avg we get 45-51=-6 and 45-36=9
adding both number -6+9=3
15+3=18 is the 9th number

Q(11-15):In each of these questions two equations (I) and (II) are given. You
have to solve both the equations and give answer
1) if x > y
2) if x ≥ y
3) if x <y
4) if x ≤ y
5) if x = y or no relation can be established between x and y
11. I. 2x² + x – 1 = 0 II. 2y² + 13y + 15 = 0
12. I. x² + 12x + 32 = 0 II. 2y² + 15y + 27 = 0
13. I. 6x² – 17x + 12 = 0 II. 7y² – 13y + 6 = 0
14. I. x² – 82x + 781 = 0 II. y² = 5041
15. I. 6x² – 47x + 80 = 0 II. 2y² – 9y + 10 = 0
