let age of yougest = x
\n" ); document.write( "the age of middle child = x+5
\n" ); document.write( "the age of oldest child = 2*x\r
\n" ); document.write( "\n" ); document.write( "given that sum of their age = 57\r
\n" ); document.write( "\n" ); document.write( "so x + (x+5) + 2*x = 57
\n" ); document.write( " 4*x + 5 =57
\n" ); document.write( " 4*x = 52
\n" ); document.write( " x = 52/4
\n" ); document.write( " x= 13
\n" ); document.write( "hence age of youngest child = 13
\n" ); document.write( " age of middle child = 13 + 5 =18
\n" ); document.write( " age of oldest child = 2*13 =26
\n" ); document.write( "
\n" ); document.write( "
\n" );
