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
