Answer:
Let the no. of one-rupee , five-rupee and ten-rupee notes be x=y=z.
Value of one-rupee notes =1x.
Value of five-rupee notes =5x.
Value of ten-rupee notes =10x.
Total value of notes = 640.
x+5x+10x= 640.
16x=640.
x=40.
So ,the no. of notes=x=y=z=40.
Total no. of notes =120.
Sorry for last mistake.
