• A. Rs. 4 lakhs
• B. Rs. 2 lakhs
• C. Rs. 4.2 lakhs
• D. Cannot be determined
• E. None of these

Answer 1

The correct option is A Rs. 4 lakhs

Expenditure of Company A in 2013 = Expenditure of Company B in 2013 = X
Income of company A in 2013 $I_1$= $X\times 1.4=1.4X$
Income of company B in 2013 $I_2$ = $X\times 1.45$
= 1.45X
$I_1+I_2$ = 1.4X +1.45X = 5.7
X =$\frac{5.7}{2.85}$ = 2
Total expenditure = 4 lakhs
