Let the 3 numbers be 'a' , 'b' and 'c' respectively and let 'a' be the largest number. Thus, we have that:
\n" ); document.write( "a+b+c=65.......(1)
\n" ); document.write( "a=b+5...........(2)
\n" ); document.write( "a=2c.............(3)
\n" ); document.write( "Thus, we have that: b=a-5(from 2) and c=0.5a
\n" ); document.write( "Substituting the alternate values of b and c(in terms of a) respectively into (1), we have:
\n" ); document.write( "a+(a-5)+0.5a=65
\n" ); document.write( "a+a-5+0.5a=65
\n" ); document.write( "2.5a=70
\n" ); document.write( "a=70/2.5=28
\n" ); document.write( "Thus, b=a-5=28-5=23 and c=0.5a=0.5*28=14
\n" ); document.write( "Therefore the numbers are 28, 23 and 14. Taadaa! :D
\n" ); document.write( "
\n" );
