average ages of 6 people is 21.
\n" ); document.write( "this means the total age is 6 * 21 = 126
\n" ); document.write( "the ages of his children are 10, 12, 15, 17, and 20.
\n" ); document.write( "the total of those 5 ages is 74.
\n" ); document.write( "126 - 74 = 52
\n" ); document.write( "the father is 52 years old.
\n" ); document.write( "total ages are now 74 + 52 = 126
\n" ); document.write( "126 / 6 = 21
\n" ); document.write( "average age of the 6 people is 21.
\n" ); document.write( "your solution is that the father's age is 52.\r
