suppose 20rs note be x.
then 10 Rs note = 8+x
value of 20 Rs note = 20*x = 20x
value of 10 Rs note = 10(8+x)=80+10x
total amount =860
20x+80+10x =860
30x = 860-80
30x = 780
x = 26 ( number of 20 Rs note)
number of 10 Rs note = 26+8=34

Answer:
No. of Notes
of 20=26
of 10=34
Step-by-step explanation:
Hii mate,
Let the number of Rs. 20 notes be x
no. of notes of Rs. 10=x+8
total money=Rs. 860
according to question,
20x+10(x+8)=860
=>20x+10x+80=860
=>30x=780
=>x=780/30=78/3 = 26
so, x+8 = 26+8 = 34
No. of notes of Rs. 20 = x = 26
No. of notes of Rs. 10 = x+8 = 34
