To solve the question, "If 6 books cost ₹615, how much do 10 books cost?", we will use the unitary method. Here’s a step-by-step breakdown of the solution:

### Step 1: Find the cost of one book.
To find the cost of one book, we divide the total cost of 6 books by the number of books.

\[ \text{Cost of one book} = \frac{615}{6} \]

### Step 2: Calculate the cost of one book.
Now we perform the division:

\[ \frac{615}{6} = 102.5 \]

So, the cost of one book is ₹102.5.

### Step 3: Find the cost of 10 books.
Now that we know the cost of one book, we can find the cost of 10 books by multiplying the cost of one book by 10.

\[ \text{Cost of 10 books} = 102.5 \times 10 \]

### Step 4: Calculate the cost of 10 books.
Now we perform the multiplication:

\[ 102.5 \times 10 = 1025 \]

So, the cost of 10 books is ₹1025.

### Final Answer:
The cost of 10 books is ₹1025.
