During a given week an author spends 1/4 of his time preparing first drafts, 3/8 of his time editing the drafts and the rest of the time in preparing final drafts. If he works 48 hours during the week, how many hours did he spend in preparing final drafts?

• 1/4+3/8 = 5/8
  rest of the time is =1-5/8 = 3/8
  3/8 * 48 =18

• he works 48 hrs in a week then 48*1/4=12 ie he spends 12hrs for preparing first drafts.then 48*3/8=18hrs for editing.so 48-(12+18)=18hrs he spend on final drafts

• 18 hrs
  total time =48hrs
  time taken in preparing drafts = 1/4*48=12
  time aken in editing and drafting = 3/8*48=18
  and rest of the time in final drafts
  48-12+18=18 hrs

• time taken to prefare first drafts=48/4=12hours
  time taken to editing the drafts =(3*48)/8=18hours
  time spend in preparing final drafts =48-(12+18)=18hours

• ANS=18
  Total work=1
  Time spend to prepare 1st draft=1-1/4=3/4
  Time spend to edit the draft=3/4-3/8=12/32=3/8
  Remaining time to prepare final draft =3/8
  If he works 48 hours during the week
  time spend =48*3/8=6*3=18

• first drafts=1/4
  editing drafts=3/8
  rest of drafts=1-(1/4+3/8)
  =3/8 this is the time to spend on final charts
  3/8th time in 48 hours is =(3/8)*48
  =18
  total time he spend preparing on final charts=18

• 126,since 7-(7/4)-(21/8)=2.14*48

• 1/4 of 100 = 25% of time spent in first draft
  3/8 of 100 = 37.5% of time spent in editing
  remaining time in percent = 62.5%
  remaining time = (48 * 62.5) / 100
  hence, remaining time = 18 hrs.
