Let $\"x\"$ = 1st no.
\n" ); document.write( " $\"%282%2F5%29%28x%29\"$ = 2nd no.
\n" ); document.write( "So,
\n" ); document.write( " $\"x%2B%282%2F5%29%28x%29=210\"$
\n" ); document.write( " $\"%285x%2B2x%29%2F5=210\"$ , cross multiply
\n" ); document.write( " $\"7x=1050\"$ ---> $\"cross%287%29x%2Fcross%287%29=cross%281050%29150%2Fcross%287%29\"$
\n" ); document.write( " $\"x=150\"$ ------------------> 1st no.
\n" ); document.write( " $\"%282%2F5%29%28150%29=300%2F50=60\"$ ---> 2nd no.
\n" ); document.write( "It follows: $\"150%2B60=210\"$
