Answer 2

Answer:

the are 100(500 notes) and 25(2000 notes)

Step-by-step explanation:

let the number of 500 notes be x and number of 2000 notes be y,

500*x+2000*y=100000

500(x+4y)=100000

x+4y=100000/500

x+4y=200 (first equation)

now,

x+y=125(second equation)

simplifying 1 and 2,

x+4y=200

-x-y=-125

3y=75

y=75/3=25 notes

x+25 notes=125

x=125-25

x=100 notes
