Answers :
Directions (1 – 5):
Percentage of males in company P = 20%
Percentage of males in company Q = 90˚ * 100/360 = 25%
Percentage of males in company R = 36˚ * 100/360 = 10%
Percentage of males in company S = 5%
Percentage of males in company T = 54˚ * 100/360 = 15%
Percentage of males in company U = 100% – (20% + 25% + 10% + 5% + 15%)
= 100% – 75% = 25%
Number of female employees in company U = 300/42.857 * 100
= 300 * 7/3 = 700
Number of male employees in company U = 700 *(100/140) = 500
Total number of male employees in all the companies together = 500 * (100/25)
= 2000
1) Answer: b)
Total number of employees in company S = 100 + 120 = 220
2) Answer: d)
Number of female employees in company Q in the year 2018
= 1200 * 2/5 = 480
Number of female employees joins in company Q in the year 2018 = 480 – 400 = 80
3) Answer: c)
Required ratio = (200 + 300): (700 – 500)
= 500: 200 = 5: 2
4) Answer: e)
Required percentage = 120/[(500 + 200 + 500)/3] * 100
= 120/400 * 100 = 30%
5) Answer: a)
Total employees in company T = 300 + 240 = 540
Number of employees like Veg = 540 * 2/3 = 360
Number of employees like Non – veg = 540 * 1/3 = 180
Number of female employees like veg = 120 * (100 + 33.33)/100
= 120 * (4/3) = 160
Number of female employees like Non – veg = 240 – 160 = 80
Number of male employees like Non – veg = 180 – 80 = 100
Required ratio = 100: 80 = 5: 4
Direction (6-10) :
6) Answer: b)
A – B = 8
C – B = 12
A + B + C = 80
B + 8 + B + 12 + B = 80
3B = 60
B = 20 years
After 10 years B’s age = 20 + 10 = 30 years
7) Answer: c)
Number of students = y
Total weight of the class = xy
Total weight of the class after reduced the weight = xy – 5 * 4 = xy – 20
(x – 2) * y = xy – 20
xy – 2y = xy – 20
2y = 20
y = 10
8) Answer: c)
Income of A = 3x
Income of B = 2x
Expenditure of A = 6y
Expenditure of B = 5y
A’s savings = 3x – 6y
A’s savings = 1/3 * 3x = x
3x – 6y = x
2x = 6y
x = 3y
B’s savings = 2x – 5y = 2x – 5 * (x/3)
= 6x – 5x/3 = x/3
Required ratio = x: x/3 = 3: 1
9) Answer: b)
Area of the rectangle = l * b
2x * x = 1440/5
x = 12 m
Length = 2 * 12 = 24 m
Breadth = 12 cm
Difference = 24 – 12 = 12 cm
10) Answer: a)
Education fee = 60/100 * x
Remaining = 40/100 * x
Food = 40/100 * x * 30/100 = 12x/100
Remaining = 40x/100 – 12x/100 = 28x/100
Shopping = 28x/100 * 50/100 = 14x/100
Remaining = 14x/100
14x/100 = 2800
x = 20000
Education fee = (20000/100) * 60 = 12000
