Show Answer
Correct Answer: 329.(5)
Solutions: (5) Expenditure of company A in 2012 = Rs. 3 lakhs (let) Expenditure of company B in 2012 = Rs. 4 lakhs (let)
For company A,
$\frac{I_{1}-3}{3}=\frac{30}{100}$
$\Rightarrow I_{1}-3=\frac{9}{10}$
$\Rightarrow I_{1}=3+\frac{9}{10}=$ Rs. $\frac{39}{10}$
khs
For company B,
$\frac{I_{2}-4}{4}=\frac{40}{100}$
$\Rightarrow I_{2}-4=\frac{8}{5}$
$\Rightarrow I_{2}=4+\frac{16}{10}=$ Rs. $\frac{56}{10}$
khs
$\therefore I_{1}: I_{2}=\frac{39}{10}: \frac{56}{10}=39: 56$
