Coffee grade 1 at sh.30. per 50 grams is blended with coffee grade 2 at sh.20 per 25grams and the mixture is sold at sh.96 per 100grams at a profit of 22%. Calculate the ratio in which the two brands of coffee were mixed.
Consider 100g of mix
If there are x g of grade 1, then the rest (100-x) is grade 2.
So now make sure that 1.22 * cost = selling price
1.22(30/50 x + 20/25 (100-x)) = 96
I was at first surprised by the result, but it makes sense. Why?
