Expenditure of Company A in the year 2010 \[=\frac{I\times 100}{%P+100}=\frac{I\times 100}{20+100}=\frac{100I}{120}=\frac{10I}{12}\] Expenditure of Company B in the year 2010 \[=\frac{100I}{150}=\frac{10I}{15}\] \[\therefore \]\[\text{Ratio}=\frac{{{E}_{A}}}{{{E}_{B}}}=\frac{15}{12}=\frac{5}{4}=5:4\]
