notes. There are 8 notes more of 10 than
20. How many notes of each kind are there? maths​

Answer 1

Answer:

No. of Rs. 10 notes = 8 + 26 = 34

No. of Rs. 20 notes = 26

Step-by-step explanation:

Let the no. of Rs. 20 notes be x

Therefore, no. of Rs. 10 notes = 8 + x.

A/Q,

20x + 10(8 + x) = 860

=> 30x = 860 - 80

=> x = 780/30

=> x = 26

Therefore,

No. of Rs. 10 notes = 8 + 26 = 34

No. of Rs. 20 notes = 26
