Show Answer

Correct Answer: (5)

Solution: (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. $\frac{39}{10}$ lakhs

For company B,

$\frac{I_{2}-4}{4}=\frac{40}{100}$

$\Rightarrow I_{2}-4=\frac{16}{10}$

$\Rightarrow I_{2}=4+\frac{16}{10}=$ Rs. $\frac{56}{10}$ lakhs

$\therefore I_{1}: I_{2}=\frac{39}{10}: \frac{56}{10}=39: 56$
