The sum of Rs 9000 is in the form of denominations of Rs 100 and Rs 500. If the total number of notes is 50, find the number of notes of each type.

Answer 1

Answer:

40 100rs notes

10 500rs notes

Step-by-step explanation:

Consider number of Rs 100 notes as A

number of Rs 500 notes as B

Given total notes is 50

A+B= 50

A=50-B

Now Total amount is rs 9000

that means

100(A)+500(B)=9000

A+5B=90

5B+(50-B)=90

4B+50=90

4B=40

B=10

A=40
