Question 353393: A rice trader mixes commercial rice that costs 29/kilo with that which costs 33/kilo. How many kilos of each should he mix to produce 200 kilos of a mixture that costs 30/kilo? Answer by robertb(4012) (Show Source):
You can put this solution on YOUR website! Let x = # kilos from 29/kilo rice. Then 200 - x = # kilos from 33/kilo rice.
Therefore he should mix 150 kilos of the 29/kilo rice and 50 kilos of the 33/kilo rice.
