Answer / swati
as i assume the time taken to complete the job is not to be
changed while increasing the employees as it does not
clearly states so..........
30 men wrk for 9 hrs
therefore for the work to be done if no of workers is
increases the no of hrs / day to work should decrease so
here s a inverse relation
solving further we get
30 = K /9 ==> K= 270
now
40 = 270/y ==> y= 6.75
therefore ans is d)none

Answer / farhan
convert days in hours so 15*9=135 hours
30 men complete a job in = 135 hours
time for 1 man to complete the same job = 135*30
time for 40 men to do the same job = 135*30/40
so the answer will be 6.75 that is (d) none

Answer / buddhika
convert days in hours so 15*9=135 hours
30 men complete a job in = 135 hours
time for 1 man to complete the same job = 135*30
time for 40 men to do the same job = 135*30/40
then the ans = 101.25
but ask no of hr per day then = 101.25/15
the the ans = 6.75

Answer / sharath
30 Men work for 15 days, if 40 men work it will be 11.25
days.
If 1 day for 30 men = 9hrs then for 40 men can work for 12
Hours in a day.
So i becomes 40/12=3.3333.
So the actual answer becomes 3.333 Hours per day.
So from the option given above the answer is (d)None.
