    Q1:

    To buy a flat, 30%of the price of the flat is paid as the down payment. If the down payment is $600000, find the price of the flat.

    C.$2000000

    Let $y be the the price of the flat

    30% y = 600000

    y=600000 / 30%

    y=2000000

    so the price of the flat is $2000000

    Q2:

    Which of the following is discrate data?

    C.the number of districts in Hong Kong

    A type of data is discrete if there are only a finite number of values possible or if there is a space on the number line between each 2 possible values.

    Therefore, for simple remember, the data can be counted is known as discrete data

    , the data have to be measured and dont know the fixed numbers is known as continuous data
