• 150 pages they can type together in 60 minutes.
  susan can type 20/10 minutes= 2/minute similarly mary can type 0.5 pages per minute together they can type 2+0.5=2.5 pages per minute
  there for, 2.5*60=150 pages /60minutes

• Susan can type 2 pages in 1 minute
  In 60min he can type 120 pages
  Mary can type 1 page in 2 minutes
  In 60min she can type 30 pages
  working together they can type 120+30 = 150 pages

  [two members can type 25 pages per 10 min

• Its too simple .......
  Work done by Susan = 20/10=2
  Work done by Mary = 5/10=1/2
  by working together =2+1/2=5/2
  Now time is given for 60 minutes so => 5/2*60=150pages

  susan can type 2 pages in 1 min so in 60 min she can type 120.
  mary can type 0ne page in 2 min so she can type 30 pages in 60 min. so 30+120=150
