Answers :

Directions (1-5):

1) Answer: B

Number of male employee in company – A = 950 + 850 – 490 = 1310

Number of female employee in company – A = 1600 + 850 – 1310 = 1140

Number of male employee in company – B = 920 + 700 – 400 = 1220

Number of female employee in company – B = 1750 + 700 – 1220 = 1230

Number of male employee in company – C = 720 + 1100 – 460 = 1360

Number of female employee in company – C = 1300 + 1100 – 1360 = 1040

Number of male employee in company – D = 1000 + 980 – 520 = 1460

Number of female employee in company – D = 1800 + 980 – 1460 = 1320

2) Answer:  C

Total number of male employee working for part-time in next year

= 110% of (850 – 490 + 700 – 400 + 1100 – 460 + 980 – 520)

= 1760 * 110/100

= 1936

Required Average = 1936/4 = 484

3) Answer:  A

Number of women working for full-time in all companies

= (1600 – 950 + 1750 – 920 +1300 – 720 + 1800 – 1000) = 2860

Average of women working for full-time in all companies

= 2860/4 = 715

And total no of employees in company A = 1600 + 850 = 2450

Required Ratio = 715: 2450 = 143: 490

4) Answer: C

Male employee of company D who working for part time = 980 – 520 = 460

Total number of employee in company B = 2450

After D join B = 2450 + 460 = 2910

% increased in company B = (460/2450) x 100 = 18.77%

5) Answer: E

 25% women of company –c who work for part time = 460 * 25% = 115

Now total woman work in full time in company – C = 115 + 580 = 695

Required percentage = (695/1360) x 100

= 51.10%

Directions (6-10) :

6) Answer: B

Pipes A and B together can fill the tank in 5 hours = (1/30 + 1/15) * 5

= 5/10 = ½

Remaining part = 1 – ½ = ½

C and D together can fill ½ of the tank in 7(9/13) hours

(1/25 + 1/x) * 100/13 = ½

1/25 + 1/x = 13/200

1/x = 5/200

1/x = 1/40

x = 40 h

7) Answer: C

(1/15 – 1/H) * 6 = 1/10

1/H = 1/15 – 1/60

1/H = 1/20

Time ratio of J and H = 2: 1

Pipe J emptied the tank in = 2/1 * 20 = 40 hours

E and J together can fill the tank = 1/25 – 1/40

= 15/1000

Required time = 200/3 hours = 66(2/3) hours

8) Answer: D

Time ratio of Pipe C and E = 8: 5

C alone fill the tank = 8/5 * 25 = 40

We cannot find the answer.

9) Answer: A

H alone empties the tank = 5/6 * 24 = 20 hours

J alone empties the tank = 10/6 * 24 = 40 hours

A + J together can fill the tank = 1/30 – 1/40 = 1/120

10) Answer: E

Required ratio = 1/15: 1/32 = 32: 15
