Answer

To solve the problem step by step, we will calculate the total cost of the books Mr. Ahuja purchased and then determine how much change he will receive after paying the shopkeeper.

### Step 1: Calculate the total cost of the Maths books
Mr. Ahuja purchased 2 Maths books at Rs. 167.50 each.

\[ \text{Total cost of Maths books} = 2 \times 167.50 = 335.00 \text{ Rs.} \]

### Step 2: Calculate the total cost of the Science book
He purchased 1 Science book at Rs. 1375.75.

\[ \text{Total cost of Science book} = 1 \times 1375.75 = 1375.75 \text{ Rs.} \]

### Step 3: Calculate the total cost of the Computer Science books
He purchased 4 Computer Science books at Rs. 168.55 each.

\[ \text{Total cost of Computer Science books} = 4 \times 168.55 = 674.20 \text{ Rs.} \]

### Step 4: Calculate the total amount spent on all books
Now, we will add the total costs of all the books together.

\[ \text{Total amount spent} = \text{Total cost of Maths books} + \text{Total cost of Science book} + \text{Total cost of Computer Science books} \]

\[ \text{Total amount spent} = 335.00 + 1375.75 + 674.20 = 2384.95 \text{ Rs.} \]

### Step 5: Calculate the total amount paid to the shopkeeper
Mr. Ahuja gave 5 notes of Rs. 500 each.

\[ \text{Total amount paid} = 5 \times 500 = 2500.00 \text{ Rs.} \]

### Step 6: Calculate the amount of change Mr. Ahuja will receive
Now, we will subtract the total amount spent from the total amount paid to find out how much change he will get back.

\[ \text{Change} = \text{Total amount paid} - \text{Total amount spent} \]

\[ \text{Change} = 2500.00 - 2384.95 = 115.05 \text{ Rs.} \]

### Final Answer
Mr. Ahuja will receive Rs. 115.05 as change.
