• B. 9:10
• C. 29:45
• D. 10:29
• E. None of these

Answer 1

The correct option is C 29:45

Income of Company B in 2010 $I_1$= 2X
Income of company B in 2013 $I_2$ = 3X
Expenditure of company B in 2010 $E_1$ $=\frac{2X}{1.50}$
Expenditure of Company B in 2013 $E_2$ $=\frac{3X}{1.45}$
$E_1:E_2\frac{2X}{1.50}:\frac{3X}{1.45}$
29:45
