• A. 41.2
• B. 38.5
• C. 44.6
• D. 36.9
• E. None of the above

Answer 1

The correct option is A 41.2

In the year 2004,
$50=\frac{I_1-12}{12}\times 100$
$\Rightarrow 12=2I_1-24$
$\Rightarrow 2I_1=36$
$\Rightarrow I_1=Rs18lakhs$ ...(i)
In the year 2005,
$60=\frac{I_2-14.5}{14.5}\times 100$
$\Rightarrow 3=\frac{I_2-14.5}{14.5}\times 5$
$\Rightarrow 3\times 14.5=5I_2-14.5\times 5$
$\Rightarrow 43.5=5I_2=72.5$
$\Rightarrow 5I_2=43.5+72.5$
$\Rightarrow I_2=\frac{116}{5}$
=Rs 23.2 lakhs
$\therefore$ Total income $=I_1+I_2$
=Rs (18+23.2) lakhs
=Rs 41.2 lakhs
