Josh had an interview for a technical job which required creativity
and problem solving skills. After a few initial questions the
interviewer handed Josh six transparent, heavy duty, sealed plastic
bags containing various hardware items. The items were Allen
wrenches, Bolts, Calipers, D-rings, Emery wheels (for dremel
tools), and Files. All items of a given type were identical. On the
table there was an accurate scale capable of measuring up to 150
ounces. The interviewer said that the task was to determine the
individual weight of each type of item without opening up any of
the bags. The interviewer stipulated that the weight of the bag
itself can be considered negligible.
After thinking for a few minutes Josh counted the number of each
type of items in each bag. He then measured and recorded the weight
of each bag. Bag one had 3 Allen wrenches, 6 Bolts, 4 Calipers, 2
D-rings, 5 Emery wheels, and 1 File. Bag two had 4 Allen wrenches,
1 Bolt, 0 Calipers, 5 D-rings, 2 Emery wheels and 3 Files. Bag
three had 1 Allen wrench, 3 Bolts, 2 Calipers, 4 D-rings, 5 Emery
wheels and 2 files. Bag four had 0 Allen wrenches, 4 Bolts, 3
Calipers, 1 D-ring, 6 Emery wheels and 4 files. Bag 5 had 2 Allen
wrenches, 5 Bolts, 5 Calipers, 3 D-rings, 4 Emery wheels, and 3
Files. Bag 6 had 1 Allen wrench, 2 Bolts, 6 Calipers, 4 D-rings, 3
Emery wheels and 3 Files.
Bag one weighed 71 ounces. Bag two weighed 57 ounces. Bag three
weighed 69 ounces. Bag four weighed 76 ounces. Bag 5 weighed 86
ounces. Bag six weighed 85 ounces.
With some effort Josh solved the problem and got the job! Can
you?
