General Electric Company has an assembly line where light bulbs are produced. The ratio of defective bulbs to good bulbs produced each day is 2 to 10. If they produce 240 bulbs, how many bulbs will NOT be defective?

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
