If q persons take y days to complete z similar jobs, how long does it take y persons to complete 1 such job?  Choose the correct choice from the following answers:  A) z  B) x  C) x/y  D) z/x  E) y/z
the Q doesn't seem to be having the any correct answer as a choice..   since we are looking for days, lets keep days in end and work out a solution..   q person can do z jobs in y days..   so q person can do 1 job in y/z days..   and 1 person can do 1 job in y^2/z days..   so y person can complete 1 job in y^2/zy=y/z..   so the answer should be y/z=y/z
<result>E</result>
If q persons take y days to complete z similar jobs, how long does it take y persons to complete 1 such job?
