Answer 1

Answer:

4 notes of 10 rupees

2 notes of 5 rupees

Answer 2

Answer:

Number of 5 rupee notes are 2 and number of 10 rupee notes are 4

Step-by-step explanation:

let number of 5 rupee note be x and 10 rupee note be y

since there are 6 notes

x+y=6--------1(x=6-y)

5x+10 y=50 (divide by 5)

x+2y=10------2

(as number of 5 rupee notes ×5 + number of 10 rupee notes ×10=50 rupees)

Substituting x from equation 1

(6-y)+2y=10

6-y=10

y=4

x=6-y

=6-4

=2
