Answers :
1) Answer: A
X * 3/4 * 4/5 * 3/4 = 900
X = 2000
2) Answer: C
Total letters = 6
Vowels = I, E = 2
Required ways = 2! * 5!
= 240
3) Answer: B
(5x + 20) / (4x + 30) = 9/10
36x + 270 = 50x + 200
14x = 70
x = 5
Number boys = 5 * 5 = 25
4) Answer: A
Speed of the boat in still water = x
60/(x – 20) = 2 * (150 / (x + 20))
60 / (x – 20) = 2 * (150 / (x + 20))
30 * (x + 20) = 150 * (x – 20)
x + 20 = 5x – 100
4x = 120
x = 30 kmph
5) Answer: C
The other number = (18 * 320 / 128) = 45
Directions (6-8) :
Total number of students from A = 80
Total number of students from B = 100
Number of students passed the exam from A = 80/100 * 80 = 64
Number of students passed the exam from B = 100 * 85/100 = 85
Number of boys passed from A = 3/8 * 72 = 27
Number of boys passed from B = 5/8 * 72 = 45
Number of girls passed the exam from A = 64 – 27 = 37
Number of girls passed the exam from B = 85 – 45 = 40
Number of girls appeared from A = 5/8 * 80 = 50
Number of boys appeared from A = 3/8 * 80 = 30
Number of girls appeared from B = 40/100 * 100 = 40
Number of boys appeared from B = 60/100 * 100 = 60
6) Answer: C
Failed students from A = 80 – 64 = 16
Failed students from B = 100 – 85 = 15
Difference = 16 – 15 = 1
7) Answer: A
Required ratio = (30 + 60):(50 + 40)
= 90:90
= 1:1
8) Answer: A
Required percentage = 37 / 40 * 100 = 92.5%
9) Answer: B
Let two parts be x and 11000 – x
(X*3*5)/100 = [(11000 – x)*9*2]/100
15x = 198000 – 18x
33x = 198000
x = 198000/33 = 6000
Two parts are Rs. 6000 and Rs. 5000
10) Answer: D
The ratio of length and breadth of the rectangular park = 3: 2(3x, 2x)
Distance = S*T = 12*(10/60) = 2 km = 2000 m
Perimeter = 2(3x + 2x)
10x = 2000
x = 200
Length = 600 m, Breadth = 400 m
Area of the park = 600*400 = 240000 Sq. m
