In: Economics
In this economy, we see that there are 2 types of alchoholic beverages consumed.
1) Rum
2) Vodka
To find out the demography percentage of consumption, let us draw a Venn Diagram.
The first circle represents the consumption of Rum and the second circle represents the consumtion of Vodka.
We see the portion where the two circles meet, represents the percentage of people who consume both rum and vodka (5%).
a) Percentage of people who do neither drink rum nor vodka;
Total Percentage Population of Men (100%) - Percentage population of men who consume Rum, Vodka or both.
100 - ( 23 + 5 + 2 ) = 100 - 30 = 70%
Therefore 70% of men do neither drink rum nor vodka.
b) Percentage of people who drink vodka but not rum = 2%
Therefore 2% of men drink vodka but not rum.
