Hi VeritasKarishma - Wanted to laser focus on the word "Units" in the expression : 100 units of Country R's currency

Lets say - Country R is France (we all know France's currency is the Euro)

Thus 100 units of Country R's currency translates to 100 units of France's currency. This then translates to 100 units of Euro (as France's currency IS the Euro)

Isn't the word "Units" redundant in the expression 100 units of Euro ?

I dont see how 100 units of Euro can be thought of as the same as 100 Euro ?

We will normally use 100 Euro but what if we do not know what the currency is?
We can say 100 units of that currency. It could translate to 100 Euros or to 100 Dollars or to 100 Yen etc

Hi VeritasKarishma - If I don't know the currency of the country but i am in need for 100 worth of amount of its currency. I think the expression i would use would be :

100 worth of amount of Country R's currency

I don't think i would say : 100 units of Country R's currency because the word units implies "number of notes" and not "amount totalling 100"

The term "units" is commonly used in Mathematics when the actual units are unknown.
e.g.
10 units of distance (means 10 metres or 10 feet or 10 inches or whatever other unit is being followed)

How do we know that the "Average" doesnt assume 101 units (100 units of the currency and 1 item of the 2%) -- so wouldnt we think to divide by 101 rather than 2?

Quote: "average (arithmetic mean) of 100 units of country R’s currency and 1 percent of one’s annual income"

Hi testtakerstrategy,

It might help to think about what exactly you are "averaging" and why. Here, we're averaging 2 things: "100 units of currency" and "1% of one's annual income", so you're probably thinking about either dividing by 2 or dividing by 101. Dividing by 101 wouldn't make much sense, since we're not asked to find the average of all of all 101 individual items (and both references are clearly in terms of the Country R's currency). The only other option would be to divide by 2, which would make sense, since we're trying to determine the calculation for the amount of income tax (and the prompt is clearly discussing the formula for that).

GMAT assassins aren't born, they're made,
