#### Solution

Let the number of five - rupee notes be x .

Therefore, the number of ten - rupee notes will be (x + 10) .

Now,

Value of five - rupee notes = Rs . 5x

Value of ten - rupee notes = Rs . 10(x + 10)

According to the question,

5x + 10(x + 10) = 1000

or 15x = 1000 - 100

or \[x = \frac{900}{15} = 60\]

∴ Number of five - rupee notes = 60 .

Number of ten - rupee notes = 60 + 10 = 70 .

Is there an error in this question or solution?
