    Answer: 200 bulbs will not be defective.

    Step-by-step explanation:

    The ratio of defective bulbs to good bulbs produced each day is 2 to 10. This ratio can also be expressed as 1 to 5 by reducing to lowest terms.

    The total ratio is the sum of the proportions.

    Total ratio = 1 + 5 = 6

    This means that if n bulbs is produced, the number of defective bulbs would be

    1/6 * n

    The number of non defective would be

    5/6 * n

    Since n = 240, then the number of bulbs that will not be defective is

    5/6 * 240 = 200 bulbs
