Earl can stuff advertising circulars into envelops at the rate of 39 envelops per minute and Ellen requires a minute and a half to stuff the same number of envelops. Working together. How long will it take earl and Ellen to stuff 325 envelops.
o 2 Minutes
o 6 minutes
o 4 minutes
o 5 minutes

• earl can do in 1 min= 39
  ellen can do in 1 min= 39*2/3=26
  therfore in 1 min both will stuff 39+26 =65 envelopes
  therfore to stuff 325 they will take =325/65= 5 min

• Ellen- in 3/2 min 39
  therefore in 1 min 39/(3/2)=26
  So in 1min Earl and Ellen stuff(39+26)=65 env
  So ans= 325/65 = 5

• Earl stuffing at a rate of 39 envelop per minute .....and by solving Ellen is stuffing at a rate of 26 envelope per minute hence there is 65 envelope stuffed in 1 min ...therefore it will take(325/65 = 5 min) to stuff 325 envelope

• earl can do in 1 sec=39/60;
  stuff can do in 1 sec=39/90;
  total time = 2sec;so work done by two in 1 sec=1/2(39/60+39/90)=13/16;
  time for 325 envelope=325*16/13=400sec=app(6min)
