Answers:
1) Answer: a)
I) x2 – 16x + 55 = 0
(x – 11) (x – 5) = 0
x = 11, 5
II) 2y2 – y – 36 = 0
2y2 + 8y – 9y – 36 = 0
2y (y + 4) – 9 (y + 4) = 0
(2y – 9) (y + 4) = 0
y = 4.5, -4
x > y
2) Answer: d)
I) 3x2 + 4x – 64 = 0
3x2 – 12x + 16x – 64 = 0
3x(x – 4) + 16(x – 4) = 0
(3x + 16) (x – 4) = 0
x = -16/3, 4 = -5.33, 4
II) 2y2 – 21y + 52 = 0
2y2 – 8y – 13y + 52 = 0
2y (y – 4) – 13 (y – 4) = 0
(2y – 13) (y – 4) = 0
y = 13/2, 4 = 6.5, 4
x ≤ y
3) Answer: d)
I) x2 + 15x + 56 = 0
(x + 8) (x + 7) = 0
x = -8, -7
II) y2 + 13y + 42 = 0
(y + 6) (y + 7) = 0
y = -6, -7
x ≤ y
4) Answer: e)
I) x2 + x – 132 = 0
(x – 11) (x + 12) = 0
x = 11, -12
II) y2 – 13y – 48 = 0
(y + 3) (y – 16) = 0
y = -3, 16
Can’t be determined
5) Answer: a)
I) x2 – 12x + 36 = 0
(x – 6) (x – 6) = 0
x = 6, 6
II) 5y2 + 4y – 12 = 0
5y2 + 10y – 6y – 12 = 0
5y (y + 2) – 6(y + 2) = 0
(5y – 6) (y + 2) = 0
y = -2, 6/5
x > y
6) Answer: a)
The total number of male eating veg from hotel A
= > 1800*(5/9)*(48/100) = 480
The total number of female eating non-veg from hotel A
= > 1800*(4/9)*(55/100) = 440
Required difference = 480 – 440 = 40
7) Answer: d)
The total number of people eating Veg from hotel B and D together
= > 2500*(2/5) + 2000*(3/5)
= > 1000 + 1200 = 2200
The total number of people eating non-veg from hotel C and E together
= > 3600*(5/9) + 2800*(4/7)
= > 2000 + 1600 = 3600
Required ratio = 2200: 3600 = 11: 18
8) Answer: b)
The total number of people eating non-veg from hotel B, C and D together
= > [2500*(3/5) + 3600*(5/9) + 2000*(2/5)]
= > [1500 + 2000 + 800] = 4300
9) Answer: c)
Total number of people eating non-veg from hotel E
= > 2800*(4/7) = 1600
Total number of people eating Veg from hotel A
= > 1800*(5/9) = 1000
Required % = (1600/1000)*100 = 160 %
10) Answer: d)
The average number of people went for hotel A and C together
= > (1800 + 3600)/2 = 2700
The average number of people went for hotel B and D together
= > (2500 + 2000)/2 = 2250
Required difference = 2700 – 2250 = 450
