For year 1997 and 1998 = ((48000 - 40000) / 40000) x 100 = 20%
For year 1999 and 2000 = ((30000 - 25000) / 25000) x 100 = 20%
is exhibited by both option (A) and (B).

500 units
1,000 units

The following bar graph shows the Income and Expenditures (in million US $) of five companies in the year 2001. The percent profit or loss of a company is given by
% Profit/Loss = (Income - Expenditure)/Expenditure x 100
Income and Expenditure (in million US $) of five companies in the year 2001.
28.28
30.30
32.32
34.34
Correct answer is B
Let the income of Company Q in 2001 = x million US $.
Then, income of Company in 2001 = ( 110/100 x x ) million US $.
Therefore 110x/100 = 40 => x = ( 400/11 )
i.e., income of Company Q in 2000 = ( 400/11 ) million US $.
Let the expenditure of Company Q in 2000 be E million US $.
Then, 20 = [(400/11) - E]/E x 100 [because %Profit = 20% ]
=> 20 = [ ( 400/11E ) - 1 ] x 100
=> E = 400/11 x 100/120 = 30.30
Therefore Expenditure of Company Q in 2000 = 30.30 million US $.
The following bar graph shows the Income and Expenditures (in million US $) of five companies in the year 2001. The percent profit or loss of a company is given by
% Profit/Loss = (Income - Expenditure)/Expenditure x 100
Income and Expenditure (in million US $) of five companies in the year 2001.
35.75
37.25
38.5
41.25
Correct answer is D
Let the expenditure of Company R in 2000 be X million US $.
Then, expenditure of Company R in 2001 = ( (120/100) x x ) million US $
Therefore 120x/100 = 45 => x = 37.5
i.e., expenditure of Company R in 2000 = 37.5 million US $
Let the income of Company R in 2000 be I million US $.
Then, 10 = (I - 37.5)/37.5 x 100 [ ∵ %Profit in 2000 = 10%]
=> I - 37.5 = 3.75
=> I = 41.25
i.e., Income of Company R in 2000 = 41.25 million US $.
