Answers :
1) Answer: e)
I) 4x2 – (4 + 2√3)x + 2√3 = 0
4x2 – 4x – 2√3x + 2√3 = 0
4x (x -1) – 2√3 (x -1) = 0
(4x – 2√3) (x – 1) = 0
x = √3/2, 1 = 0.866, 1
II) 8y2 – (24 + 3√3)y + 9√3 = 0
8y2 – 24y – 3√3y + 9√3 = 0
8y(y – 3) – 3√3 (y – 3) = 0
(8y – 3√3) (y – 3) = 0
y = 3√3/8, 3 = 0.64, 3
Can’t be determined
2) Answer: d)
I) 3x2 + 41x + 138 = 0
3x2 + 18x + 23x + 138 = 0
3x (x + 6) + 23 (x + 6) = 0
(3x + 23) (x + 6) = 0
X = -23/3, -6 = -6, -7.66
II) 4y2 + 12y – 72 = 0
4y2 + 24y – 12y – 72 = 0
4y (y + 6) – 12 (y + 6) = 0
(4y – 12) (y + 6) = 0
Y = 3, -6
x  ≤ y
3) Answer: e)
I) 2x2 – 8x – 64 = 0
2x2 + 8x – 16x – 64 = 0
2x (x + 4) – 16 (x + 4) = 0
(2x – 16) (x + 4) = 0
X = 8, – 4
II) 4y2 – 28y – 72 = 0
4y2 + 8y – 36y – 72 = 0
4y (y + 2) – 36 (y + 2) = 0
(4y – 36) (y + 2) = 0
Y = 9, -2
Can’t be determined
4) Answer: a)
I) 10x2 – 17x + 7 = 0
10x2 – 10x – 7x + 7 = 0
10x(x – 1) – 7(x – 1) = 0
(10x – 7) (x – 1) = 0
X = 7/10, 1 = 0.7, 1
II) 15y2 – 19y + 6 = 0
15y2 -10y – 9y + 6 = 0
5y (3y – 2) – 3 (3y – 2) = 0
(5y – 3) (3y – 2) = 0
Y = 3/5, 2/3
X > y
5) Answer: c)
I) 6x2 + 31x + 35 = 0
6x2 + 21x + 10x + 35 = 0
3x (2x + 7) + 5 (2x + 7) = 0
(3x + 5) (2x + 7) = 0
X = -5/3, -7/2
II) 2y2 + 3y + 1= 0
2y2 + 2y + y + 1= 0
2y(y + 1) + 1(y + 1) = 0
(2y + 1) (y + 1) = 0
Y = -1/2, -1
X < y
6) Answer: c)
The total number of peoples using Airtel services all the given years together
= > 68 + 72 + 80 + 85 + 90
= > 395 lakhs
Required average = 395/5 = 79 lakhs
7) Answer: b)
Total number of peoples using all three given services together in the year 2012
= > 36 + 68 + 56 = 160 lakhs
Total number of peoples using all three given services together in the year 2014
= > 48 + 80 + 62 = 190 lakhs
Required % = (160/190)*100 = 84.21 % = 85 %
8) Answer: d)
The total number of peoples using BSNL services in all the given years together
= > 36 + 45 + 48 + 52 + 55 = 236 lakhs
The total number of peoples using all three given services together in the year 2013 and 2015 together
= > 45 + 72 + 60 + 52 + 85 + 66 = 380 lakhs
Required difference = 380 – 236 = 144 lakhs
9) Answer: a)
The total number of peoples using Vodafone in the year 2012, 2014 and 2016 together
= > 56 + 62 + 70 = 188 lakhs
The total number of people using all three given services together in the year 2016
= > 55 + 90 + 70 = 215 lakhs
Required ratio = 188 : 215
10) Answer: c)
Total number of people using Vodafone in the year 2013 and 2016 together
= > 60 + 70 = 130 lakhs
Total number of people using Airtel in the year 2014 = 80 lakhs
