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=100/25=4
  price of 1 book= 100/15=20/3
  for travelling expenses=rs15(15%of100)
  remaining amount=rs85
  cost of 5 pencils=4*5=20
  now remaining amount=rs65
  in 1rs ---------- 3/20 books can purchased
  so in rs65 -------- 3/20*65=39/4=9 3/4
  so 9 books he can purchase with remaining money.

• total money in the pocket=100
  with 100rs the person can buy 25 pencils ----------each pencil cost=100/25=4rs
  with 100rs the person can buy 15 books ------------each book cost= 100/15=20/3
  traveling expences= 15% of 100rs=15rs
  remaining total money=85rs
  he brought 5 pencils cost of 5pencils=5*4rs=20rs
  net balance=85-20=65rs
  with 65rs how many books we can brought
  i.e, 1 book =20/3rs
  xbooks=65rs
  criss cross the above equations x*(20/3)=65*1
  x=65*(3/20)
  x=39/4 i.e, nearly equal to 40/4
  if shop keeper is kind we get 10 books.
  else if shop keeper is conjus we get 9 books only.

• he has bought 5 pencil , so he has money to buy 10 pencil more.
  
  price of 25 pencil= price of 15 book
  1 pencil =15/25
  10 pencil=15/25 * 10 = 6 book
  so , by the remaining money he can buy 10 pencil or 6 book.

  Each pencil costs Rs. 4/-
  Hence for 5 pencils it is Rs. 20/-
  Amount left with him is Rs. 65/-
  Each book costs Rs. 6.6/-
  Hence he can buy 9 books with the remaining money.
