Well, we are living in 2013 right now so by simple subtraction, you would find that a 42 year-old was born in 1971 (2013- 42 = 1971)
If you were born in 1942 then you would have your 68th birthday in 2010
It's 2021 and if you are 42 to then you were born in 1979 (2021 - 42 = 1979)
42 years previous to the current year.
If you turn 42 in the year 2012 then you were born in 1970.
People born in 1970 will be 42 in 2012.
1969
1969
2017 − 42 = 1975 was the year of birth.
1967
Take the current year and subtract 42 from it. For example, if the year was 1962, then subtracting 42 from it would equal 1920.
1968. To figure that out you subtract the year now to 42. So it would be 2010-42 and that equals 1968.
1968
As today is the 1st January 2010, you were born in the year 1967.
