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
