venu and renu's ages are in the ratio of 4 : 5\r
\n" ); document.write( "\n" ); document.write( "let the common multiple be x\r
\n" ); document.write( "\n" ); document.write( "their ages will be 4x & 5x repectively\r
\n" ); document.write( "\n" ); document.write( "After 6 years\r
\n" ); document.write( "\n" ); document.write( "their ages will be 4x+6 & 5x+6 repectively\r
\n" ); document.write( "\n" ); document.write( " $\"%284x%2B6%29%2F%285x%2B6%29=+5%2F6\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cross multiply\r
\n" ); document.write( "\n" ); document.write( "6(4x+6)=5(5x+6)\r
\n" ); document.write( "\n" ); document.write( "24x+36=25x+30\r
\n" ); document.write( "\n" ); document.write( "bring the variables on one side\r
\n" ); document.write( "\n" ); document.write( "24x-25x=30-36\r
\n" ); document.write( "\n" ); document.write( "-x=-6\r
\n" ); document.write( "\n" ); document.write( "so x=6\r
\n" ); document.write( "\n" ); document.write( "Venu's age = 4x = 4*6 = 24 years
\n" ); document.write( "Renu's age = 5x=5*6=30 years\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
