The idea is to subtract, in this case, 2015 - 20.
The information provided contains an inconsistency, as a person cannot be both 15 years old in 2015 and 20 years old in 2010. If the person was 15 in 2015, they would have been born in 2000. Conversely, if they were 20 in 2010, they would have been born in 1990. Therefore, the ages stated do not align correctly.
6 percent of 1000 is 60 - whether now, 20 years ago or 20 years from now.
People turning twenty in 2015 were born in 1995.
20
score like 4 score and 7 years ago our fathers... score like 4 score and 7 years ago our fathers...
If your passport expired 20 years ago, it would have expired in current year - 20.
This year is 2017, so 2017-20 = 1997

20 years ago which is 1992

If your passport expired 20 years ago, it means it expired in the year 2001.
the population of Manitoba 20 years ago was 943,153 persons
It seems like around 20-15 years ago it got cable.
It would be 20 because if we are in 2020 and we take away 2000 we would be left with 20 years
