Answers :
Directions (1-6) :
1) Answer: C
Required percentage = 400/1440 * 100 = 28%
2) Answer: B
Average male employees from HDFC, BOB and ICICI = (1800 + 900 + 840)/3
= 1180
Average female employee from SBI and IOB = (1200 + 960)/2 = 1080
Difference = 1180 – 1080 = 100
3) Answer: B
Required ratio = (600 + 600): (1200 + 800)
= 1200: 2000
= 3: 5
4) Answer: C
Required average = (600 + 1200 + 960 + 900 + 400)/5
= 812
5) Answer: A
Required percentage = 800/2160 * 100
= 37%
6) Answer: A
Difference = 2400 – 1800 = 600
Directions (7-8) :
7) Answer: E
(319.897 ÷ √65) + 50.12 % of 119.92 =?
320/8 + 1/2 * 120 =?
? = 100
8) Answer: B
8.912 * 6.076 + 65.102 % of 39.912 + 5.902 * 2.101 =?
54 + 26 + 12 =?
92 =?
Directions (9-10):
9) Answer: E
x2Â + 24x + 119 = 0
x2Â + 17x + 7x + 119 = 0
x(x + 17) + 7(x + 17) = 0
(x + 7)(x + 17) = 0
x = -7, -17
y2Â + 13y + 42 = 0
y2Â + 6y + 7y + 42 = 0
y(y + 6) + 7(y + 6) = 0
(y + 7)(y + 6) = 0
Y = -7, -6
Hence, x ≤ y
10) Answer: C
x2 – 19x + 88 = 0
x2 – 11x – 8x + 88 = 0
x(x – 11) – 8(x – 11) = 0
(x – 8)(x – 11) = 0
x = 8, 11
y2 – 21y + 104 = 0
y2 – 8y – 13y + 104 = 0
y(y – 8) – 13(y – 8) = 0
(y – 13)(y – 8) = 0
y = 13, 8
Relationship between x and y cannot be established.
