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.

• 15 books 100 rupees
  therefore 3 books is 20 rupees
  and cost of 25 books is 100 rupees
  therefore 1 book is 4 rupees
  traveling expenses = 15 rupees
  5 pencils = 5*4 = 20 rupees
  remaining 100 - 35 = 65 rupees
  cost of 9 books is 20*3 = 60 rupees
  so total 9 books can be purchased and balance amount is 5 rupees

• ans is 10books with 5rs remaining.
  he has 100rs.
  he can buy 25 pencils or 15 books
  thats a pencil cost is 4 rs.
  and book cost is 6.(100/15=6.666 take 6 rs only)
  travelling expenses 15%, 100-15=85.
  now he has 85 only.
  he purchased 5 pencils , one pencil is 4 rs
  so 5*4=20.
  85-20=65.(now he has).
  out of 65 he can purchase 10 books only with remaining of 5rs.
  so ans is 10 books and 5 rs remaining
