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
