Answer:
17 notes of 500 and 8 notes of 100
Step-by-step explanation:
let total note of 500 be x.
hence, total notes of 100 = ( x-9)
(x*500) + (100*{x-9}) = 9300
500x + 100x-900=9300
600x-900=9300
600x =9300+900
600x = 10200
x = 10200/600
x = 17
total 500 notes =x=17 notes
total 100 notes =-9= 8 notes
