You can put this solution on YOUR website!
Let father age = x years
\n" ); document.write( "thus, boy age = x/4 years\r
\n" ); document.write( "\n" ); document.write( "x + x/4 < 80
\n" ); document.write( "5x/4 < 80
\n" ); document.write( "5x < 320
\n" ); document.write( "x<64\r
\n" ); document.write( "\n" ); document.write( "So, possible solutions are
\n" ); document.write( "Father's age = 60 years, Boy's age = 15 years
\n" ); document.write( "Father's age = 56 years, Boy's age = 14 years
\n" ); document.write( "Father's age = 52 years, Boy's age = 13 years
\n" ); document.write( "Father's age = 48 years, Boy's age = 12 years
\n" ); document.write( "Father's age = 44 years, Boy's age = 11 years
\n" ); document.write( "Father's age = 40 years, Boy's age = 10 years
\n" ); document.write( "Father's age = 36 years, Boy's age = 9 years
\n" ); document.write( "Father's age = 32 years, Boy's age = 8 years
\n" ); document.write( "Father's age = 28 years, Boy's age = 7 years
\n" ); document.write( "Father's age = 24 years, Boy's age = 6 years
\n" ); document.write( "Father's age = 20 years, Boy's age = 5 years \n" ); document.write( "

\n" );
