Question
18 skilled workers can complete a task in 12 days while
24 semi-skilled workers need 15 days to complete the same task. 12 skilled workers started the task but 3 of them left after a few days. How many semi-skilled workers should replace the 3 skilled ones who left so that the task can be completed in stipulated time?Solution
Let the skilled workers =x and semi-skilled workers=y 18x ×12 =24y ×15 3x =5y 3 skilled workers =5 semi-skilled workers. Therefore, we can say that in place of 3 skilled workers, 5 semi workers can come.
