Question 64
In what ratio should cement costing Rs 250 per bag be mixed with cement costing Rs 325 per bag so that the cost of the mixture is Rs 300 per bag. (A bag of cement is 50 kg).
Solution
Let the amount of cement costing 250/kg be x and cement costing 325/Kg be y
Now total cost will be same
so we get
250x+325y=300x+300y
50x=25y
x:y =1:2
