Question

Percentage is a very important concept in Maths. To understand, please observe the following example carefully:

If there is a 50 ml Lemon water in a glass Out of which 40 ml is water And the remaining solution is the lemon.

Then what is the percentage of lemon?

Quantity of lemon = 50 ml - 40 ml = 10 ml

% of Lemon= ( Quantity of lemon in lemon water )/( Total Quantity of lemon water including lemon and water )*100

So, in the above example % of lemon = (10 / 50) * 100 = 20%

Keeping in mind above, now solve the following questions:

If in one glass there is 120 ml water and 30 ml lemon, then what is the percentage of lemon? Please think and answer carefully.
