The table below presents the percentage profit earned by two companies A and B during the period 2013 to 2018. Based on the data given in the table, answer five questions that follow Yearwise percentage (%) profit [Where profit % = $\frac{Income − Expenditure}{Expenditure} × 100]$Year % Profit Earned A B 2013 20 % 35 % 2014 32 % 30 % 2015 40 % 50 % 2016 25 % 40 % 2017 30 % 30 % 2018 15 % 40 %
In which year is the ratio of income to expenditure of company A the maximum?
2015
To determine the year in which the ratio of income to expenditure of company A is the maximum, we need to understand the relationship between income, expenditure, and profit percentage. The profit percentage of a company is given by the formula:
\(\text{Profit \%} = \left(\frac{\text{Income} - \text{Expenditure}}{\text{Expenditure}}\right) \times 100\)
From the formula, we can derive the ratio of income to expenditure as follows:
\(\frac{\text{Income}}{\text{Expenditure}} = 1 + \frac{\text{Profit \%}}{100}\)
We'll now calculate this ratio for each year based on the profit percentage given for company A:
By comparing these calculated ratios, we see that the highest ratio of income to expenditure occurs in 2015, where the ratio is 1.40.
Thus, the year in which the ratio of income to expenditure of company A is the maximum is 2015.
In company E, if the average number of employees who are Graduates in Arts and Commerce is 377, then the number of employees in company E is
In company B, the difference between the number of employees who are Graduates in Arts and Graduates in Science is:
In company A, if the ratio between the number of employees who are graduates in Commerce and Arts is 10:7, then the number of employees who are graduates in Arts in the same Company is:
In Company B, if the number of employees increased by 20% from December 2021 to December 2022 and 20% of the total number of employees in December 2022 are Science Graduates, then the number of employees who are Science Graduates in December 2022, is:
If the number of employees in company D is 3 times the number of employees in Company C and the difference between the number of employees who are Arts Graduates in company D and that in company C is 480, then the number of employees in company C is
