A small metal shop operates 10 hours each day, producing 100 parts/hour. If productivity were increased 20%, how many hours would the plant have to work to produce 1000 parts?

The plant would have to work 8.33 hours

Explanation:

Initial productivity:

100 parts were produced in 1 hour

Percentage increase in productivity = 20%

New productivity:

100 + (100 × 0.2) = 100 + 20 = 120

120 parts would be produced in 1 hour

Number of hours the plant would have to work to produce 1000 parts = 1000/120 = 8.33 hours

there's 11 people for the 1st position. then, no matter who gets it, there's only 10 left for the second, and then 9 left for the third. 11 x 10 x 9 = 990.   the answer is there are 990 different ways the positions can be filled by these applicants
