E.None of these

Number of sales employees from C = 1200 – 400 – 500 = 300

Required difference = 400 – 300 = 100

3x + 3x + 4x + 400 + 400 = 1800

10x = 1000

x = 100

Number of sales employees in E = 4 * 100 = 400

Total number of employees in E = 400 + 500 + 300 = 1200

Number of sales employees in C = 1200 – 500 – 400 = 300 = Number of sales employees in A

Total number of employees from A = 300 + 400 + 200 = 900

Number of IT employees from D = 1900 – 200 – 300 – 400 – 500 = 500

Required percentage = (500 – 400)/400 * 100 = 25%

Number of HR employees from B = 1900 – (400 + 500 + 600 + 300) = 100

Total number of employees from B = 100 + 400 + 300 = 800

Let the CP be Rs.100.

MP = Rs.140 and SP = 85/100 * 140 = Rs.119

He cheats by giving 10% less in weight.

CP = 100 * 90/100 = Rs.90

Profit % = (119 – 90)/90 * 100 = 32.22% ≈ 32%

Let us take the speed of boat and speed of current be x and y respectively.

x + y = 8/5 * (x – y)

= > x/y = 13/3

Required percentage = 3/13 * 100 = 23%

Probability of selecting a bag = ½

Probability of getting white ball from first bag = 3/7

Probability of getting white ball from second bag = 3/5

Required probability = ½ * 3/7 + ½ * 3/5 = 3/14 + 3/10 = 18/35

Number of students passed be x.

Total marks = 100 * 23 = 35x + (100 – x) * 20

=> 2300 = 35x + 2000 – 20x

=> x = 20

Let the present age of A and B be 5x and 6x.

D = 6x – 10 and C = 41 – 5x

(B + C + D)/3 = 22

=> 6x + 41 – 5x + 6x – 10 = 66

=> x = 5

D’s age = 6x – 10 = 30 – 10 = 20

C’s age = 41 – 5x = 41 – 25 = 16

Required difference = D – C

= 20 – 16 = 4
