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.

Q:

If the price of a commodity is decreased by 20% and its consumption is increased by 10%, what will be the increase or decrease in the expenditure on the commodity?

A) increase 12% B) decrease 12%
C) increase 16% D) decrease 16%

Given the price of a commodity is decreased by  p = 20%

And its consumption is increased by q = 10%

Now, required increase or decrease in the expenditure on the commodity can be 

p + q + pq/100 = -20 + 10 - 200/100 = -10 - 2 = -12%.

 

Hence, decrease in the expenditure = 12%

Remaining work = 1 - 2/3 = 1/3

Let men required men for working remaining days be 'm'

So men required = (120 x 64)/2 = (m x 60)/1 => m = 64

Men discharge = 120 – 64 = 56 men.
