The ticket to Disneyland will cost anywhere from 1p to 63p.You need to produce the exact change as the ticket counter and have with you a 63p coin.So you decide to break this into change but you want to carry with you as few coins as possible. Assuming that coins of all denominations are available,how many coins(denominations) would you split the 63 p into?

• for such ques keep on dividing the given no by 2,
  63/2
  31/2--1
  15/2--1
  7/2--1
  3/2--1
  1--1
  now 1+1+1+1+1+1=6
