Let x = current age of Sony
\n" ); document.write( " so 4x = current age of Raju\r
\n" ); document.write( "\n" ); document.write( " x - 5 = age of Sony 5 years ago
\n" ); document.write( " 4x - 5 = age of Raju 5 years ago\r
\n" ); document.write( "\n" ); document.write( "4x - 5 = 7(x - 5)
\n" ); document.write( "4x - 5 = 7x - 35
\n" ); document.write( "-3x = -30
\n" ); document.write( "x = 10\r
\n" ); document.write( "\n" ); document.write( "Therefore, Sony is 10 years old and Raju is 40 years old.
