The following bar graph shows the incomes and expenditures (in million rupees) of three companies in the year 2020. Study the graph and answer the question that follows.

Which company earned the maximum percentage profit (Profit is calculated on expenditure) in the year 2020, and by what percentage?

Correct option is C

लाभ तभी होता है जब आय व्यय से अधिक हो, इसलिए केवल कंपनी B लाभ में है।

​$$\text{Percentage Profit} = \left( \frac{50 - 40}{40} \right) \times 100 = \left( \frac{10}{40} \right) \times 100 = 25\%```$$​​
अधिकतम प्रतिशत लाभ कंपनी बी द्वारा 25% अर्जित किया जाता है।
