4. A person has Rs 100/- in his pocket, he can as 25 pencils or 15books. He kept 15% of the money for
travelling expenses and purchased 5 pencils.So how many books he can purchase with the remaining
money.

• price of 1 pencil rs 4
  price of 1 book = 100/15 = Rs 20/3
  
  amt left after travelling expenses and purchasing 5 pencils = 100-15-20 = Rs 65
  No of books that can be bought = 65*3/20 = 39/4 = 9.75
  
  so 9 books can be bought.
