Let the age of the son = x
\n" ); document.write( "Then the age of his father = x+30
\n" ); document.write( "Given,father will be only thrice as old as the son after 5 years
\n" ); document.write( " x+30+5 = 3(x+5)
\n" ); document.write( " x+35 = 3x+15
\n" ); document.write( " 35-15 = 3x-x
\n" ); document.write( " 20 = 2x
\n" ); document.write( " 2x = 20
\n" ); document.write( " x = 20/2 = 10
\n" ); document.write( "Therefore the age of his father = x+30 = 10+30 = 45 years
\n" ); document.write( "
\n" ); document.write( "
