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

The concentration of the resulting solution is 10%.

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=(20)/(100)*4`

`A=(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=(0.8)/(8)* 100`

`C=10\%`

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