The mean of 4 numbers is 25, so their total must be 100.....\"4x%2F4=25\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Each number is decreased by 10 and there are four numbers, so they decrease by 40 in total.....\"4%2A10=40\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%28100-40%29%2F4=15\"
\n" ); document.write( "The mean of the numbers that were decreased is 15.
