Answer

1. ANSWER : D 


Explanation -  Required difference 


= (272 + 240 + 236 + 256 + 288) - (200 + 224 + 248 + 272 + 260)


= 88. 


 


2. ANSWER : B 


Explanation -  Total number of Peons working in the Company in 1999 


= (820 + 184 + 152 + 196 + 224) - (96 + 88 + 80 + 120)


= 1192. 


 


3. ANSWER : A 


Explanation - Number of Managers working in the Company: 


In 1995 = 760.
In 2000 = (760 + 280 + 179 + 148 + 160 + 193) - (120 + 92 + 88 + 72 + 96)= 1252.


Therefore, Percentage increase in the number of Managers  


=1252-760760×100 %= 64.74%  


Number of Technicians working in the Company:
In 1995 = 1200.
In 2000 = (1200 + 272 + 240 + 236 + 256 + 288) - (120 + 128 + 96 + 100 +112) = 1936.

Therefore, Percentage increase in the number of Technicians 


 = 1936-12001200×100 % = 61.33%


Number of Operators working in the Company:


In 1995 = 880.
In 2000 = (880 + 256 + 240 + 208 + 192 + 248) -  (104 + 120 + 100 + 112 + 144) = 1444.

Therefore, Percentage increase in the number of Operators  


=1444-880880×100 % = 64.09% 


Number of Accountants working in the Company: 


In 1995 = 1160.
In 2000 = (1160 + 200 + 224 + 248 + 272 + 260) -  (100 + 104 + 96 + 88 + 92) = 1884.

Therefore, Percentage increase in the number of Accountants  


=1884-11601160×100 % = 62.14% 


Number of Peons working in the Company: 


In 1995 = 820.
In 2000 = (820 + 184 + 152 + 196 + 224 + 200) - (96 + 88 + 80 + 120 + 104)    = 1288.

Therefore, Percentage increase in the number of Peons  


=1288-820820×100 % = 57.07% 


Clearly, the percentage increase is maximum in case of Managers.


 


4. ANSWER : B 


Explanation  -  Total number of employees of various categories working in the Company in 1997 are: 


Managers = (760 + 280 + 179) - (120 + 92) = 1007.


Technicians = (1200 + 272 + 240) - (120 + 128) = 1464.


Operators = (880 + 256 + 240) - (104 + 120) = 1152.


Accountants = (1160 + 200 + 224) - (100 + 104) = 1380.


Peons = (820 + 184 + 152) - (96 + 88) = 972.


Therefore, Pooled average of all the five categories of employees working in the Company in 1997 = 1/5 x (1007 + 1464 + 1152 + 1380 + 972)


= 1/5 x (5975)


= 1195.


 


5. ANSWER : D 


Explanation  - Total number of Operators who left the Company during 1995 - 2000 


= (104 + 120 + 100 + 112 + 144)


= 580.


Total number of Operators who joined the Company during 1995 - 2000

= (880 + 256 + 240 + 208 + 192 + 248

= 2024.

Therefore, Required Percentage

= (580/2024)x100% = 28.66% ~= 29%.

Q:

A coin is tossed 5 times. What is the probability that head appears an odd number of times?

A) 1/2 B) 1/3
C) 2/3 D) 1
 
Answer & Explanation Answer: A) 1/2

Explanation:

The possible outcomes are as follows :

5H, 5T, (H, 4T), (T, 4H), (2H, 3T) (3H, 2T), i.e. 6 outcomes in all.

Therefore the probability that head appears an odd number of times = 3/6 =1/2 (In only three outcomes out of the six outcomes, head appears an odd number of times).
