Question

pls solve the question step by step​

Answer 1

Step-by-step explanation:

x+x+10=1000

2x+10=1000

2x=990

x=495

5 rupee=495

10 rupee=505

Answer 2

Step-by-step explanation:

Let no. of. 10 rupee notes = y

And no. of. 5 rupee notes = x

Then, y =x + 10

We know,

The value of 10 rupee notes + value of 5 rupee notes = total value.

So, 10y + 5x =1000

10(x + 10) + 5x = 1000

10x + 100 + 5x = 1000

15x = 1000-100

x = 900/15

x = 60

So, y = 60 + 10 =70

Thus, you have 70 10rupee notes and 60 5rupee notes.
