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 % $=\dfrac{Income-Expenditure}{Expenditure}\times 100$
The total sum of profit percent of company H in all given years together is approximately what percent more or less than the total sum of profit percent of company I in all given years together?
Solution
H $\rightarrow$ 285%
I $\rightarrow$ 325%
Required% $ = \dfrac{325-285}{325}\times 100$
$=\dfrac{40}{325}\times 100$
$= 12.3076 \approx 12\%$ less
