total number of notes is 90, find the number of notes of each denomination.

Answer 1

Answer

10 rs=10

5rs= 80

Step-by-step explanation:

let rs 5 note be x

rs 10= x-90

value of 5rs note= 5x

value of 10rs note= 10(90-x);

5x+10(90-x)=500

5x+900-10x=500

-5x=500-900

-5x=-400

x=-400/-5

x=80
