Problema Solution
A rice retailer would like to sell rice worth P20.00 per kilo. He has 40 kilos of NFA rice worth P18.00 per kilo in his rice box. How many kilos of sinandomeng rice worth P28 will he mix to the rice box?
Answer provided by our tutors
let 'x' represent the addition of 28 per kilo of rice, then '40+x' represents the kilo of rice ended up as 28 per kilo
the following equation expresses the ratios:
20(x+40) = 28x + 40*18
------------------
------------------
x=10
So 10 kilos of P28 rice should be added.
