# Calcium and citality

The daily dose of calcium obtained using 0.75 liters of milk and 60 grams of cheese.

A/ At the morning I drank half a liter of milk. How much cheese I must eatto eat a daily dose of calcium?

b / I ate 50 grams of cheese, how much milk I must drink?

c / How many times I overshoot daily dose, when I drank one liter of milk and ate 100 grams of cheese?

Result

a =  20 g
b =  0.125 l
c =  2

#### Solution:

$a=60 \cdot \ (1-0.5/0.75)=20 \ \text{g}$
$b=0.75 \cdot \ (1-50/60)=\dfrac{ 1 }{ 8 }=0.125 \ \text{l}$
$c=1/0.75+100/60-1=2$
