How many different sums can be formed with the coins,5 rupee,1 rupee,50 paisa,25 paisa,10 paisa and 1 paisa?

• total no. of combination = 6C1+6C2+6C3+6C4+6C5+6C6
  => 2^6-1 (As nC0+nC1+......+nCn = 2^n i.e including zero)

• there r 6 coins
  every coin have 2 possibility(either selected or rejected)
  so 2^6
  now in 2^6 there is also a possiblity comes...if no coins is selected
  so total possible solution=2^6-1=63
