Let the number of five rupess notes are x
Number of ten rupees notes are x + 10
Amount due to five rupees notes = 5 \(\times\) x = 5x
Amount due to ten rupees notes = 10(x + 10) = 10x + 100
According to the question total amount = Rs 1000
5x + 10x + 100 = 1000
15x = 900
x = 60
Therefore the number of five rupess notes are 60
Number of ten rupees notes are x + 10 = 60 + 10 = 70
