Directions (set of 3 questions): Read the following line graph carefully and answer the questions given below.
Line graph shows percent profit earned by two companies H and I over the years.
Profit % $=\dfrac{Income-Expenditure}{Expenditure}\times 100$
If the incomes of company H in 2013 and 2017 are in the ratio 4 : 5 respectively, what is the ratio of the expenditures of that company in these two years?
Solution
$\dfrac{{{E_{2013}}}\times 140 \%}{{{E}_{2017}}\times 160\%}=\dfrac{4}{5}$
$\dfrac{{{E}_{2013}}}{{{E}_{2017}}}=\dfrac{4}{5}\times \dfrac{16}{14}=\dfrac{32}{35} = 32:35$
