Price ratio of A,B is 2:3 in general m:n
\n" ); document.write( "sold out ratio of A,B is 4:5 in general p:q
\n" ); document.write( "revenue ratio of A,B always will be 2*4:3*5 in general mp:nq
\n" ); document.write( "As total revenue is 27000, and their ratio is 8:15 say(8x,15x)
\n" ); document.write( "we have the exact revenue as follows, 8x+15x=27600
\n" ); document.write( " 23x=27600
\n" ); document.write( " x=27600/23 ==> x=1200 that is we have the exact revenue ratio as of A is 8x=8*1200=9600\r
\n" ); document.write( "\n" ); document.write( " B is 15x=15*1200=18000
\n" ); document.write( "
