Using new equipment, a worker finished 4 more parts in an hour than was planned and fulfilled his daily task not in 8 hours,
but in 6 hours. How many parts did the worker have to finish during the day according to the schedule?
~~~~~~~~~~~~~~~~~~~ 

Let the old rate is "r" parts per hour (now unknown value).


The condition says: Now he produces 4 more parts in one hour than before in 6 hours:

                    In other words, the new rate R = 6r+4  parts per hour.


Working at this rate, he will produce 8*R = 8*(6r+4) = 48r + 32 parts in  8-hour working day.


That is all that we can say: nothing more and nothing less.


At given condition IT IS NOT POSSIBLE to get a concrete value as a single answer.

-------------------------
So, I'd say: this description is as clear as it is at the dark night with no light.
