Let the number of Rs 5 notes be x
Hence the number of Rs 10 notes be (90 − x)
Total sum of money = Rs 500
∴ 5x + 10 (90 − x) = 500
5x + 900 − 10x = 500
− 5x = 500 − 900 = −400
∴ x = 80
Hence there are 80 notes of Rs 5 and 10 notes of Rs 10.

Total amount =500
Let ₹5 notes be x and ₹10 notes be y
Money in the form of 5=5x
In the form of 10=10y
5x+10y=500
X+y=90
By solving this we get
X=80
Y=10
