Q:

The average monthly salary of the employees of a firm is Rs.60 out of the employees 12 officers get an average of Rs.400 per month and the rest an average of Rs. 56 per month , Find the number of emp

Answer

Actual average salary of 12 officers = 400


\inline \fn_jvn \therefore Total salary of 12 officers = 400 x 12 = 4800


Average of these 12  officers as a whole =60


Total salary of 12 officers as a whole = 60 x 12 = 720


The total salary of rest  = 4800 - 720 = 4080


Difference in average of the rest of officers  = 60 - 56 = 4


Rest of the officers = \inline \fn_jvn \frac{4080}{4}=1020


Total number of employees = 1020 + 12 = 1032

Answer

1. ANSWERS  : D  


Explanation-   Required difference = (128000 - 107000) = 21000.


 


2. ANSWERS  : C  


Explanation-  From the line-graph it is clear that the productions of Company X in the   years 1997, 1998, 1999, 2000, 2001 and 2002 are 119000, 99000, 141000, 78000, 120000 and 159000 and those of Company Y are 139000, 120000,100000, 128000, 107000 and 148000 respectively. 


Total production of Company X from 1997 to 2002 


= 119000 + 99000 + 141000 + 78000 + 120000 + 159000 


= 716000. 


and total production of Company Y from 1997 to 2002 


= 139000 + 120000 + 100000 + 128000 + 107000 + 148000 


= 742000. 


Difference = (742000 - 716000) = 26000.


 


3. ANSWERS  : A 


Explanation-  Average number of vehicles manufactured by Company X  


16×119000+99000+141000+78000+120000+159000 


 = 119333.


 


4. ANSWERS  : D  


Explanation-   The difference between the productions of Companies X and Y in various years are: 


 For 1997 (139000 - 119000)  = 20000. 


 For 1998 (120000 - 99000)  = 21000. 


 For 1999 (141000 - 100000)  = 41000. 


 For 2000 (128000 - 78000) = 50000. 


 For 2001 (120000 - 107000) = 13000. 


 For 2002 (159000 - 148000) = 11000. 


 Clearly, maximum difference was in 2000.


 


5. ANSWERS  :  B

Q:

A room is 6 meters 24 centimeters in length and 4 meters 32 centimeters in Width. Find the least number of square tiles of equal size required to cover the entire floor of the room.

A) 107 B) 117
C) 127 D) 137
 
Answer & Explanation Answer: B) 117

Explanation:

Let us calculate both the length and width of the room in centimeters.

Length = 6 meters and 24 centimeters = 624 cm

width = 4 meters and 32 centimeters = 432 cm

As we want the least number of square tiles required, it means the length of each square tile should be as large as possible.Further,the length of each square tile should be a factor of both the length and width of the room.

Hence, the length of each square tile will be equal to the HCF of the length and width of the room = HCF of 624 and 432 = 48

Thus, the number of square tiles required = (624 x 432 ) / (48 x 48) = 13 x 9 = 117

Q:

If y/(x - z) = (y + x)/z = x/y then find z : y : x ?

A) 1:2:3 B) 3:2:4
C) 4:3:2 D) 2:3:4
 
Answer & Explanation Answer: B) 3:2:4

Explanation:

Given, y/(x - z) = (y + x)/z = x/y
yz = xy + x2 - yz - xz ....(1)
Also xy = yx-z x2 -xz = y2 ....(2)
Using (1) and (2), we get yz = xy - yz + y2
2yz = xy + y2
2z = x + y
Only option (B) satisfies the equation.
