Question

Maria has added 4 liters of pure water to 4 liters of a 20% sugar syrup. What is the concentration of the resulting solution?

Answer 1

The concentration of the resulting syrup is 10 liters.

Answer 2

Answer:

The concentration of the resulting solution is 10%.

Step-by-step explanation:

Given : Maria has added 4 liters of pure water to 4 liters of a 20% sugar syrup.

To find : What is the concentration of the resulting solution?

Solution :

Maria has 4 liters of a 20% sugar syrup,

i.e. $A=20\%\text{ of }4$

$A=\frac{20}{100}\times4$

$A=\frac{4}{5}$

$A=0.8$

She add 4 liters of pure water to 4 liter

New solution is 4+4=8 liters

The concentration of the resulting solution is

$C=\frac{0.8}{8}\times 100$

$C=10\%$

Therefore, The concentration of the resulting solution is 10%.
