How to do this question?
1) Suppose incomes in Country A (0,0,0,10) incomes in Country B are (1,2,3,4) incomes in Country C are (2.5,2.5,2.5,2.5). Country _________________ will Lorenz dominate the other two, while country ________________ will have a higher Gini coefficient than the other two.

2) If 1 CAD = 0.80 USD, and 1 USD = 0.50 EUR, then we can conclude that:
a. 1 CAD= 1.30 EUR
b. 1 CAD= 0.40 EUR
c. 1 EUR= 0.25 CAD
d. 1 EUR= 1.30 CAD

How do you suppose to approach these questions?

2) you view as percentages. Do simple math and you have your answer.
