2)
I) 2x2 – 13x + 18 = 0
II) 3y2 + 4y – 15 = 0
3)
I) 4x2 + 14x + 12 = 0
II) 3y2 + 18y + 27 = 0

Answers:
1) Answer: b)
I) x2 – 18x + 72 = 0
(x – 12) (x – 6) = 0
X = 12, 6
II) y2 + 2y – 48 = 0
(y – 6) (y + 8) = 0
y = 6, -8
X ≥ y
2) Answer: a)
I) 2x2 – 13x + 18 = 0
2x2 – 4x – 9x + 18 = 0
2x (x – 2) -9 (x – 2) = 0
(2x – 9) (x – 2) = 0
X = 9/2, 2 = 4.5, 2
II) 3y2 + 4y – 15 = 0
3y2 + 9y – 5y – 15 = 0
3y (y + 3) – 5 (y + 3) = 0
(3y – 5) (y + 3) = 0
Y = 5/3, -3 = 1.667, -3
X > y
3) Answer: a)
I) 4x2 + 14x + 12 = 0
4x2 + 8x + 6x + 12 = 0
4x (x + 2) + 6(x + 2) = 0
(4x + 6) (x + 2) = 0
X = -6/4, -2 = -1.5, -2
II) 3y2 + 18y + 27 = 0
3y2 + 9y + 9y + 27 = 0
3y (y + 3) + 9 (y + 3) = 0
(3y + 9) (y + 3) = 0
Y = -9/3, -3 = -3, -3
X > y
4) Answer: e)
I) x2 – 4x – 77 = 0
(x – 11) (x + 7) = 0
X = 11, -7
II) y2 + 20y + 64 = 0
(y + 16) (y + 4) = 0
Y = -16, -4
Relationship cannot be determined
5) Answer: c)
3x + 5y = -22 –> (1)
2x – 3y = -2 –> (2)
By solving the equation (1) and (2), we get,
X = -4, y = -2
X < y
Directions (6-10):
6) Answer: a)
The total number of Staffs in Institution A
= > (660/11)*1 = 60
The total number of Staffs in Institution C
= > (588/98)*12 = 72
Required difference = 72 – 60 = 12
7) Answer: d)
The total number of students in Institution B
= > (345/69)*80 = 400
The total number of students in Institution C
= > (588/98)*110 = 660
Required ratio = 400: 660 = 20: 33
8) Answer: b)
The total number of Students in Institution A, C and D together
= > [(660/11)*12] + [(588/98)*110] + [(855/19)*20]
= > 720 + 660 + 900 = 2280
Required average = 2280/3 = 760
9) Answer: c)
Total number of staffs in Institution B
= > (345/69)*11 = 55
Total number of staffs in Institution E
= > (1008/14)*1 = 72
Required % = (55/72)*100 = 76 %
10) Answer: a)
The sum of the total number of staffs in Institution A, B and D together
= > [(660/11)*1] + [(345/69)*11] + [(855/19)*1]
= > 60 + 55 + 45 = 160
