Answer:
The Return On Investment (ROI) is 1000%
Step-by-step explanation:
First, we calculate the cost of previous year defects
= Cost per defective product x The number of products that are defective
Previous Year Defect Costs = $100 x 2000 = $200,000
Secondly, we calculate the cost of defects after training took place
= Cost per defective product x defects (1000)
= $100 x 1000= $100,000
After training therefore, the savings in defect costs will be
$200,000 - $100,000 = $100,000
Thirdly, we calculate the cost of training
= Cost of training per worker x number of workers
= $100 x 100 workers = $10,000
Finally, calculate the Return on Investment in percentage
= (The Savings in cost of defects/ cost incurred to train the works) x100
= ($100,000/$10,000) = 1000%
The Return on Investment is 1000%
