Three grades A, B and C of rice were mixed in the ratio 3:4:5
\n" ); document.write( " the cost per kilogram of each of the grades A, B and C were sh.120.00, sh.90.00 and sh. 60.00 respectively. calculate:
\n" ); document.write( ":
\n" ); document.write( "A) the cost of one kilogram of the mixture.
\n" ); document.write( "three fractions: \"3%2F12+%2B+4%2F12+%2B+5%2F12\" = 1
\n" ); document.write( "Cost of 1 kilo times these fractions
\n" ); document.write( "A: \"3%2F12\"*120 = 30
\n" ); document.write( "B: \"4%2F12\" *90 = 30
\n" ); document.write( "C: \"5%2F12\" *60 = 25
\n" ); document.write( "--------------------------
\n" ); document.write( "Cost of 1 kilo: 85
\n" ); document.write( ":
\n" ); document.write( "B) the selling price of 5 kilogram of the mixture given that the mixture was sold at 8% profit
\n" ); document.write( "1.08(5*85) = 459 is the retail price of 5 kilos
\n" ); document.write( "
\n" );
