1
What is the income (in rupee) of Company C in the year 2011?
» Explain it
C
Income = Expenditure + Expenditure × Profit%

Therefore, Income of Company C2011 = 25.4 + 25.4 ×  21.5  
100

= 25.4 + 5.461 = Rs 30.861 crore

Hence, option C is correct.

2
What is the difference between the profits of Company A and Company B in the year 2012?
» Explain it
B
Profit of Company A2012 = 23.2 ×  31.5  = 7.308
100

Profit of Company B2012 = 24.8 ×  27.5  = 6.82
100

∴   Difference = 7.308 – 6.820 = 0.488 crore = 48.8 lakh.

Hence, option B is correct.

3
The expenditure of Company A in the year 2007 and 2012 together is approximately what percent of the expenditure of Company C in the year 2008 and 2010 together?
» Explain it
D
Expenditure of Company A(2007 + 2012) = 17.8 + 23.2 = 41 crore

Expenditure of Company C(2008 + 2010) = 27.5 + 22.5 = 50 crore

Reqd % =  41  × 100 = 82%
50

Hence, option D is correct.

4
The percentage profit of Company C in the year 2009 is approximately what per cent more or less than the percentage profit of Company A in the year 2007?
» Explain it
B
% profit of Company C2009 = 28.4%

% profit of Company C2007 = 16.2%

∴   Reqd % =  28.4 – 16.2  × 100
16.2

=   12.2  × 100 = 75.3% = 75%
16.2

Hence, option B is correct.

5
The income of Company B in the year 2010 is approximately what percent of the expenditure of Company A in the year 2009?
» Explain it
C
Income = Expenditure + Expenditure × Profit%

Therefore, Income of Company B2010 = 23 + 23 ×  25  
100

= 23 + 5.75 = 28.75 crore

Expenditure of Company A2009 = 21 crore

∴    Reqd % =  28.75  × 100 = 136.9 ≈ 137%
21

Hence, option C is correct.
