The problem you shared from the image is as follows:

Problem:
A purse contains ₹250 in notes of denominations ₹10 and ₹50. If the number of ₹10 notes is one more than that of ₹50 notes, find the number of notes of each denomination.

Solution:

Let the number of ₹50 notes be x.

• The number of ₹10 notes is x + 1 (as given in the problem).

Now, let's form an equation based on the total amount:

• The value of ₹50 notes = $50 \times x$
• The value of ₹10 notes = $10 \times (x + 1)$

According to the problem, the total value of these notes is ₹250. Therefore, the equation becomes: $50x + 10(x + 1) = 250$

Now, solve this equation:

1. Expand the equation: $50x + 10x + 10 = 250$

2. Combine like terms: $60x + 10 = 250$

3. Subtract 10 from both sides: $60x = 240$

4. Divide by 60: $x = 4$
