Answer» A=20/kg,B=24/kg ,C =30/kg lets assume x kg be rice A, y kg be rice B and 2 kgs is rice C Given FINAL CP = 25 So, 20x+24y+60=25(x+y+2) ------(1) By Solving above EQ. y=10-5x Since , y cannot be zero or negative Hence, x can only be 1 giving y = 5KG A=20/kg,B=24/kg ,C =30/kg lets assume x kg be rice A, y kg be rice B and 2 kgs is rice C Given final CP = 25 So, 20x+24y+60=25(x+y+2) ------(1) By Solving above eq. y=10-5x Since , y cannot be zero or negative Hence, x can only be 1 giving y = 5kg |
