**:**

__Answer Key with Solution__**1. (A);**Number of male employees in unit C for company X

= 14% of 2500 ร (3/7) = 150

Number of female employees in unit C for company Y

= 15% of 3000 ร (1/3) = 150

**2. (E);**Number of female employees of company Y in unit E

= 22% of 3000 ร 1/3 = 220

Number of male employees of company X in unit E

= 10% of 2500 ร 2/5 = 100

:. Required more % = (220-100)/100 ร 100

= 120%

**3. (B);**Number of male employees in different units for company Y : A = 300,

B = 240, C = 300, D = 100, E = 440 and F = 150.

Hence, our answer is A and C.

**4. (C);**Required ratio = (10%of 2500ร2/5) / (15% of 3000ร1/3)= 2 : 3

**5. (A);**Number of female employees for company Y in different units:

A = 60, B = 300, C = 150, D = 500, E = 220 and F = 240

**6. (C);**Average population (in thousands) of both the towns in 1994

= (45+44+48+45)/2

= 45 + 22 + 24 = 91 and that in 1998

= (50+47+50+47)/ 2

= 50 + 47 = 97

:. Required percentage increase = (6/91) ร 100

= 6.59% Approx. 7%.

**7. (B);**Required ratio

**8. (A);**Population of X and Y in 1996

= (50 + 47+47 + 48 ) ร 1000 = 192000

Population of X and Y in 1994

= (45 + 44 + 48 + 45) ร 1000 = 182000

Now, 192 ร 1000 = x ร 182 ร 1000

:. x = (192/182) = 1.05

**9. (B);**Average number of females for

X =1/5 (45 + 47 + 48 + 50 + 47) ร 1000

= 237 ร 200 = 47400

Y =1/5 (48 + 49 + 47 + 50 + 50) ร 1000

= 244 ร 200 = 48800

So, 1994, 1995 and 1998 are the three desired years for X and 1994 and 1996

are the two desired years for Y. Hence the required number of years is four

(1994, 1995, 1996 and 1998).

**10. (B)**

In 1994 โ (45000 โ 44000) = 1000

In 1995 โ (47000 – 44000) = 3000

In 1996 โ (48000 โ 47000) = 1000

In 1997 โ (50000 โ 48000) = 2000

In 1998 โ (47000 โ 47000) = 0
