Answer:

c) 120 notes of Rs.50, 80 notes of Rs.100

Explanation:
Let x be the number of Rs.50 notes and y be the number of Rs.100 notes.
From the given information:
1. x + y = 200 (total number of notes)
2. 50x + 100y = 15500 (total amount)

Solving these equations, we find x = 120 and y = 80, indicating 120 Rs.50 notes and 80 Rs.100 notes.
