I divided it into three periods
\n" ); document.write( "David was the only investors for 6 months so he gets all the profit for that period\r
\n" ); document.write( "\n" ); document.write( "10000 for 12 months
\n" ); document.write( "15000 for 6 months 1/2
\n" ); document.write( "20000 for 4 months 1/3\r
\n" ); document.write( "\n" ); document.write( "10000 for 6 months 6/12 1450 d 1/2 of the year\r
\n" ); document.write( "\n" ); document.write( "john and david were the only investors for 2 months 1/6 of the year
\n" ); document.write( "10000+15000 for 2 months 2/12 483.33
\n" ); document.write( "david had 2/5 and john had 3/5 of the investment
\n" ); document.write( "d 10/25=2/5 96.66*2 193.33
\n" ); document.write( "j 15/25=3/5 96.66*3 290.00\r
\n" ); document.write( "\n" ); document.write( "all three were investors for the last four months 1/3 of the year\r
\n" ); document.write( "\n" ); document.write( "10000+15000+20000 for 4/12 966.67
\n" ); document.write( "proportion of the investments
\n" ); document.write( "d 10/45 j 15/45 p 20/45\r
\n" ); document.write( "\n" ); document.write( "21.48*10 214.81 d
\n" ); document.write( "21.48*15 322.22 j
\n" ); document.write( "21.48*20 429.63 p\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "david =1450+193.33+214.81=$1858.14
\n" ); document.write( "john=290+322.22=$612.22
\n" ); document.write( "peter =$429.63\r
\n" ); document.write( "\n" ); document.write( "That is how I see it.
