Let Rs50 notes be x and Rs100 notes be y.
Total number of notes -->
x + y = 900...........(i)
Total amount ---->
50x + 100y = 55000
=> x + 2y = 1100...........(ii)
Solving eq (i) and (ii),
y = 200
Putting the value of y = 200 in eq(i),
=>x + 200 = 900
=> x = 700
Hence, number of Rs50 notes = 700
Number of Rs100 notes = 200
