In a camp, there was enough food to feed 2000 people on equal rations for 90 days.
\n" ); document.write( " After 20 days, 500 more people joined the camp.
\n" ); document.write( " Calculate the number of days that the remaining food would be used to feed the people.
\n" ); document.write( ":
\n" ); document.write( "Find how many meal-man days available
\n" ); document.write( "2000 * 90 = 180000
\n" ); document.write( ":
\n" ); document.write( "let d = no. of remaining days available when 500 men added
\n" ); document.write( ":
\n" ); document.write( "20(2000) + 2500d = 180000
\n" ); document.write( "40000 + 2500d = 180000
\n" ); document.write( "simplify, divide by 100
\n" ); document.write( "400 + 25d = 1800
\n" ); document.write( "25d = 1800 - 400
\n" ); document.write( "25d = 1400
\n" ); document.write( "d = 1400/25
\n" ); document.write( "d = 56 days of food after the increase to 2500 men \n" ); document.write( "
\n" );
