Answers :
Directions (1 – 5):
1) Answer: A
Required percentage = (200/450) * 100 = 44.44%
2) Answer: D
Average = (360 + 360 + 160 + 450 + 160) / 5 = 298
3) Answer: B
Required ratio = 240: 240 = 1: 1
4) Answer: A
Number of IT employees = 480 * 7/12 = 280
Number of HR employees = 480 * 5/12 = 200
Number of male employees from IT = 360 * ¾ = 270
Number of male employees from HR = 360 * 1/4 =90
Number of female employees from IT = 280 – 270 = 10
Number of female employees from HR = 200 – 90 = 110
Required ratio = 10: 110
= 1: 11
5) Answer: B
Required percentage = (160/720) * 100 = 22.22%
Directions (6-10) :
6) Answer: C
SI = P * N * R/100
7680 – 4800 = 4800 * x * 4/100
x = 15%
SI received by B = 4800 * (15 + 3) * 5/100
= 4320
7) Answer: C
Profit ratio of A and B = 4500 * 12: x * 8
=6750: x
6750/x + 6750 = 9000/17000
9x + 6750 * 9 = 17 * 6750
9x = 54000
x = 6000
8) Answer: A
(4x + 6 + 12)/(5x + 6 + 12) = 7/8
(4x + 18) * 8 = (5x + 18) * 7
32x + 144 = 35x + 126
3x = 18
x = 6 years
Preset age ratio of Shon to Sania= (4 * 6 + 6):(5 * 6 + 6)
= 30: 36
=5: 6
9) Answer: B
Perimeter of the square = 112 cm
Side of the square = 112/4 = 28 cm
Surface area of sphere= 4 * 22/7 * r * r
5544 = 4 * 22/7 * r * r
Radius of the sphere = 21 cm
Required ratio = 28: 21
= 4: 3
10) Answer: A
C complete the whole work in = 4/1 * 5 = 20 days
B/80 = C/100
B/C = 4/5
B = 5/4 * 20 = 25 days
A = 100/250 * 25 = 10 days
A + B + C = 1/20 + 1/25 + 1/10
= 5 + 4 + 10/100
=100/19 days
= 5(5/19) days
