The information provided details the financial performance of four companies (A, B, C, and D) based on their revenue, cost incurred, and profit:
Company A:
Company B:
Company C:
Company D:
Based on the given data, Company C had the highest annual profit, which is 85.
The information provided adds details about the financial performance of the companies in three years and specifies that for all companies, cost incurred is less than revenue, except for Company D in 2020, where the revenue is 20 and the cost incurred is 50.
Additionally, it is mentioned that Company D experienced the highest annual loss in 2020, given the revenue of 20 and cost incurred of 50. The loss can be calculated as follows:
Loss = Revenue - Cost Incurred = 20 - 50 = -30
Therefore, Company D experienced a loss of 30 in 2020, representing the highest annual loss among the mentioned companies and years.
Measure of A's performance in 2019 =90-85/85=5/85=0.06
Measure of A's performance in 2019 =100-75/75=25/75=0.33
Measure of A's performance in 2019 =25-20/25=5/25=0.2
Measure of A's performance in 2019 =50-40/40=10/40=0.25
Company A had the lowest value

Consequently, Company B experienced the least total number of employees leaving in 2019 and 2020.

Five countries engage in trade with each other. Each country levies import tariffs on the other countries. The import tariff levied by Country X on Country Y is calculated by multiplying the corresponding tariff percentage with the total imports of Country X from Country Y. The radar chart below depicts different import tariff percentages charged by each of the five countries on the others. For example, US (the blue line in the chart) charges 20%, 40%, 30%, and 30% import tariff percentages on imports from France, India, Japan, and UK, respectively. The bar chart depicts the import tariffs levied by each county on other countries. For example, US charged import tariff of 3 billion USD on UK.
Assume that imports from one country to an other equals the exports from the latter to the former. The trade surplus of Country X with Country Y is defined as follows. Trade surplus = Exports from Country X to Country Y Imports to Country X from Country Y. A negative trade surplus is called trade deficit.
