each page of a book having a specific dimension has a border of 10% of size of a page.for each inch of page there are 6 lines.a girl can complete book in 1 hr which has 100 pages.find out how much time another girl would take to read 300 pages having same dimension with 20% border in each page??

• Ans=2hr.40 min.
  For Ist case->Readable part of page=90%,so Actual pages read in 1 hr=0.9*100=90
  For IInd case->Readable part of page=80%,so pages to be read=0.8*300=240
  For 90 pages it took 1 hr,so for 240,time taken=240*1/90=8/3=2 2/3hr.
  
  (*It is assumed that speed of another girl is same as the first girl and
  each inch of pages contains same no. of lines in both the cases)
