Answer:
Step-by-step explanation:
Let the number of Rs 5 notes be x
Total number of notes = 90
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
-5x = −400
∴ x = 80
Hence there are 80 notes of Rs 5
Number of Rs 10 notes = 90 - 80 = 10
Hence there are 10 notes of Rs 10.
