    Answer: 16.67%

    Explanation:

    You need to learn how to calculate percent to be able to perform this type of problems by yourself.

    Percent is the ratio of a quantity on base to 100 parts.

    In this case the increase is 5 students of an initial group of 30, so you need to find the equivalent expression with a base of 100 instead of 30.   That is, you need to find the ratio with denominator 100 equivalent to the ratio 5/30:

      x         5
    —— = —-
    100      30

    => x = (5 / 30) * 100 = 16.67%.

    Also, you should notice that calculatind the percent is done dividing the parts by the whole and multiplying by 100, i.e. (5 / 30) * 100, which is the same done above.
