.

We have notes of three different nominations and coins of four different nominations.


In all, there are notes and coins of  3 + 4 = 7  different nominations.


Each of them may go with the coefficient 1 or 0.


Hence, in all, we have   = 128  different opportunities (including one empty = zero opportunity).

Comment from student: a big thanks to you mam but i am sorry to say that its ans. is 127.

My response. It is because I admitted the empty case, which corresponds to the zero value.

If to exclude it, you will get exactly 127 opportunities.
