Data is a collection of information, which can be presented in many forms. One of them is tabular form in which data can be analysed and it helps to understand the data. Here, we have to find the percentage/ relative frequency using the data given in the table.

The correct answer is: 15%


    In the question a table is given using the table find the percentage of girls have blonde hair.
    According to the given table,
    Total number of people = 40

    The percentage of girls having blonde hair= 6 over 40 cross times 100 equals 15 percent sign
    So, the percentage of girls having blonde hair is 15%.

    Percent is referred as per hundred which means the ratio of given number and 100. Percent can be calculated by using the formula fraction numerator v a l u e over denominator t o t a l space v a l u e end fraction cross times 100.
