• Ans - 50 page
  solution - Lets he reading first days = x page
  then second day = x+1
  third day = x+2
  fourth days=x+3
  fifth days = x+4
  sixth days = x+5
  seventh days = x+6
  Eight days = x+7
  Nineth days = x+8
  then add total
  9x+36=414
  x=414-36/9
  = 50 page
  so last day he reading 50 page

• 50 pages
  An arithmetic series of 9 terms and difference of 1 with sum 414
  If a=first term then,(9/2)(2a+8*1)=414 or a=42
  And 9th term=42+8*1=50
  So on last 9th day pages read=50
