Entry ticket to an exhibition ranges from 1p to 31p. You need to provide exact change at the counter. You have 31p coin. In how many parts will u divide 31p so that u will provide the exact change required and carry as less coins as possible?

• 31=1+2+4+8+16
  if u divide 31p into above 5 parts u can provide the exact change required and carry as less coins as possible.
  so ans should be 5.
  i think the options are wrong.

• we have paise in denotations of 1,2,5 and 10
  so to carry min amount, we can use 3 10p coins and one 1p coin which takes just 4 coins in total.
  
  i guess the question provided is incomplete
