Answer 2

Answer:

Thus Rs 50 notes=90

and Rs 100 notes=110

Step-by-step explanation:

let Rs 50 notes=x

and Rs 100 notes=y

Then sum of notes

=x+y= 200......................(1)

sum of Rs 50 notes=50x

and sum of Rs 50 notes=100y

Total amount=50x+100y=15500

x+2y =310..................(2)

Subtracting (1) from (2) we get

y=310-200=110

Thus from(1)

x=200-110=90

Thus Rs 50 notes=90

and Rs 100 notes=110
