Answer 2

Answer:

Explanation:

def make_amount(rupees_to_make,no_of_five,no_of_one):

   five_needed=0

   one_needed=0

       

   five_needed = int(rupees_to_make / 5)

   one_needed = rupees_to_make % 5

   if (five_needed <= no_of_five and one_needed <= no_of_one):

       print("No. of Five needed :", five_needed)

       print("No. of One needed  :", one_needed)

   else:

       print(-1)

make_amount(28,8,5)
