Let the Rs 100 notes be X.
Then the Rs 500 notes be (50-X).
Value of Rs 100notes = 100×X = 100x
Value of Rs 500 notes = 500(50- X)
=25000- 500X
A/Q 100X + 25000-500X = Rs 9000
or -400X = 9000-25000
or -400X = -16000
therefore, X = 16000/400 = 40
Rs 100 notes = X = 40 notes
Rs 500 notes = 50-40 = 10 notes
