Answer 2

Answer:

Answer: I added 35 ml of Lemon to the water.

Step-by-step explanation:

There are water in the glass= 140ml

We added a little lemon to create lemon water solution such that there is 20% lemon in it.

So according to question, Lemon in the solution= 20%

Let the total solution (Water+ Lemon) = 100%

If Lemon is 20% , then water percentage in the solution= Solution % - Lemon %

So water percentage = 100% - 20% = 80%

Then, according to the question,

$80 \: percent \: = 140 \: ml$

$1 \: percent \: = \frac{140}{80}$

$100 \: percent \: = \frac{140}{80} \times 100$

$= 175 \: ml$

So the total solution is 175 ml.

Then, Lemon in the solution= 20% of 175 ml

$= \frac{20}{100} \times 175$

$= \frac{3500}{100}$

$= 35 \: ml$

Conclusion:

So I added 35 ml of the lemon to water to make the Lemon water solution.
