\n" ); document.write( "Let a = no. of yrs when C will \"1%2F3\" Dad's projected age
\n" ); document.write( ":
\n" ); document.write( "10 + a = \"1%2F3\"(52+a)
\n" ); document.write( "multiply both sides by 3
\n" ); document.write( "3(10+a) = 52 + a
\n" ); document.write( "30 + 3a = 52 + a
\n" ); document.write( "3a - a = 52 - 30
\n" ); document.write( "2a = 22
\n" ); document.write( "a = 11 yrs for this to be true
\n" ); document.write( "then
