Show Answer

Correct Answer: (2)

Solution: (2)

Income of company B in $2009 =$ Rs. $I_{1}$ , lakhs

$∴ \frac{I_{1} - E_{1}}{E_{1}} \times 100 = 35$

$\Rightarrow \frac{I_{1} - 12}{12} = \frac{35}{100} = \frac{7}{20}$

$\Rightarrow \frac{I_{1} - 12}{3} = \frac{7}{5}$

$\Rightarrow 5 I_{1} - 60 = 21$

$\Rightarrow 5 I_{1} = 60 + 21 = 81$

$\Rightarrow I_{1} = \frac{81}{5} =$ Rs. 16.2 lakhs

Similarly,

$\frac{I_{2} - 14.5}{14.5} = \frac{50}{100} = \frac{1}{2}$ $\Rightarrow 2 I_{2} - 29 = 14.5$

$\Rightarrow 2 I_{2} = 29 + 14.5 = 43.5$

$\Rightarrow I_{2} = \frac{43.5}{2} =$ Rs. 21.75 lakhs

$∴ I_{1} + I_{2} =$ Rs. $(16.2 + 21.75)$ lakhs $=$ Rs. 37.95 lakhs
