133 – 7 = 2190

143 – 8 = 2736

153 – 9 = 3366

163 – 10 = 4086

173 – 11 = 4902

183 – 12 = 5820

3 * 9 + 1 = 28

28 * 7 + 1 = 197

197 * 5 + 1 = 986

986 * 3 + 1 = 2959

2959 * 1 + 1 = 2960

17 + 23 = 25

25 + 53 = 150

150 + 83 = 662

662 + 113 = 1993

1993 + 143 = 4737

4737 + 173 = 9650

24 * 1 = 24

24 * 1.5 = 36

36 * 2 = 72

72 * 2.5 = 180

180 * 3 = 540

1260 ÷ 6 = 210

210 ÷ 5 = 42

42 ÷ 4 = 10.5

10.5 ÷ 3 = 3.5

3.5 ÷ 2 = 1.75

Directions (6-10) :

Number of employees from B = x

Number of employees from A = x * 150/100 = 3x/2

Number of employees from C = 2x

Number of employees from D = 2x * 125/100 = 5x/2

(3x/2 + 2x + 5x/2) = 1440

12x = 1440 * 2

X = 240

Total number of employees in A = 3/2 * 240 = 360

Total number of employees in D = 5/2 * 240 = 600

Total number of employee in C = 2 * 240 = 480

Total number of employee in B = 240

Number of female employees in D = 2y

Number of male employees in D = 3y

2y + 3y = 600

5y = 600

Y = 120

Number of male employees in D = 3 * 120 = 360

Number of female employees in D = 120 * 2 = 240

Number of male employees in B = z

Number of female employees in B = z * 60/100

z + 3z/5 = 240

8z = 240 * 5

Z= 150

Number of female employees in B = 150 * 60/100 = 90

Number of male employees in A = 150 + 50 = 200

Number of female employees in A = 360 – 200 = 160

Number of female employees in C = 100 + 90 =190

Number of male employees in C = 480 – 190 = 290 Average number of female employees = (160 + 90 + 190 + 240)/4 = 170

From Quantity I,

Required Sum = 200 + 150 = 350

From Quantity II,

Number of male employees in D = 360

Quantity I < Quantity II

Difference = 290 – 160 = 130

Required percentage = ((200 + 360) – 480)/480 * 100 = 16.67%

Required ratio = (200 + 360 + 150 + 290): (160 + 90 + 190 + 240)

= 1000: 680

= 25: 17
