Answers :
Directions (1 – 5):
1) Answer: c)
5x – 4y = -7 –> (1)
3x – 5y = 1 –> (2)
By solving the equation (1) and (2), we get,
x = -3, y = -2
x < y
2) Answer: e)
I) 2x2 + 2x – 12 = 0
2x2 + 6x – 4x – 12 = 0
2x (x + 3) – 4 (x + 3) = 0
(2x – 4) (x + 3) = 0
x = 2, -3
II) 3y2 – 2y – 8 = 0
3y2 – 6y + 4y – 8 = 0
3y (y – 2) + 4 (y – 2) = 0
(3y + 4) (y – 2) = 0
y = -4/3, 2 = -1.33, 2
Can’t be determined
3) Answer: e)
I) 4x2 – 8x – 32 = 0
4x2 – 16x + 8x – 32 = 0
4x (x – 4) + 8 (x – 4) = 0
(4x + 8) (x – 4) = 0
x = -2, 4
II) 2y2 – 3y – 27 = 0
2y2 + 6y – 9y – 27 = 0
2y (y + 3) – 9 (y + 3) = 0
(2y – 9) (y + 3) = 0
y = 9/2, -3 = 4.5, -3
Can’t be determined
4) Answer: a)
I) 3x2 + 8x + 5 = 0
3x2 + 3x + 5x + 5 = 0
3x (x + 1) + 5 (x + 1) = 0
(3x + 5) (x + 1) = 0
x = -5/3, -1 = -1.67, -1
II) 4y2 + 15y + 14 = 0
4y2 + 8y+ 7y + 14 = 0
4y (y + 2) + 7 (y + 2) = 0
(4y + 7) (y + 2) = 0
y = -7/4, -2 = – 1.75, – 2
x > y
5) Answer: d)
I) x2 – 5x + 6 = 0
(x – 3) (x – 2) = 0
x = 3, 2
II) y2 – 8y + 15 = 0
(y – 3) (y – 5) = 0
y = 3, 5
x ≤ y
Directions (Q. 6 – 10):
6) Answer: c)
The total female using Samsung mobile from city P
= > 21000*(48/100) = 10080
The total male using Nokia mobile from city T
= > 25000*(3/5) = 15000
Required difference = 15000 – 10080 = 4920
7) Answer: a)
The total number of Samsung users in all the given cities together
= > (21 + 28 + 19 + 24 + 15) thousands
= > 107000
The total number of Redmi users in all the given cities together
= > (16 + 12 + 22 + 20 + 18) thousands
= > 88000
Required ratio = 107000: 88000 = 107: 88
8) Answer: d)
The average number of Nokia users in all the given cities together
= > (21000 + 17000 + 26000 + 23000 + 25000)/5
= > 112000/5 = 22400
9) Answer: b)
Total mobile phone users in city Q of all the given brands together
= > 28000 + 12000 + 17000 = 57000
Total mobile phone users of city S of all the given brands together
= > 24000 + 20000 + 23000 = 67000
Required % = [(67000 – 57000)/67000]*100 = 15 % less
10) Answer: c)
Total number of female using Redmi mobile from the city Q and R together
= > 12000*(40/100) + 22000*(54/100)
= > 4800 + 11880 = 16680
Total number of male using Nokia mobile from city P and T together
= > 21000*(8/15) + 25000*(2/5)
= > 11200 + 10000 = 21200
Required % = (16680/21200)*100 = 78.667 % = 79 %
