Question

860 is put in a box, in 20 notes and 10
notes. There are 8 notes more of 10 than
20. How many notes of each kind are there?​

Answer 1

Answer:

Step-by-step explanation:

Let,the no.of 20 notes be x

Then,the no.of 10 notes will be 8+x

According to given condition

x+(8+x) = 860

x+8+x = 860

2x+8 = 860

2x= 860-8

2x = 852

x = 852/2

x = 426

Thus,no.of 20 notes(x) = 426

Then,no.of 10 notes(8+x) = 8+426= 434
