Question

Three friends were born in consecutive years. The sum of their birth year is 6,039. Find the year in which the youngest person was born.

Answer 1

Divide the total by the number of friends (3), this will give you the middle year.

6039 / 3 = 2013

Now subtract 1 from that for the earliest year:

2013 -1 = 2012

Add 1 to the middle year for the latest year:

2013 +1 = 2014

The youngest person would be the one born in the latest year, which would be 2014.
