Answer

To find out how much money Reshma gets back after buying the fruits, we need to calculate the total cost of the fruits she bought and then subtract that from the amount she paid (Rs. 500).

### Step-by-Step Solution:

1. **Calculate the cost of Watermelon:**
- Price per kg = Rs. 18.50
- Quantity = 4.5 kg
- Cost = Price per kg × Quantity
- Cost of Watermelon = 18.50 × 4.5 = Rs. 83.25

2. **Calculate the cost of Cherries:**
- Price per kg = Rs. 72
- Quantity = 1 kg 200 g = 1.2 kg (since 200 g = 0.2 kg)
- Cost = Price per kg × Quantity
- Cost of Cherries = 72 × 1.2 = Rs. 86.40

3. **Calculate the cost of Grapes:**
- Price per kg = Rs. 120.60
- Quantity = 250 g = 0.25 kg
- Cost = Price per kg × Quantity
- Cost of Grapes = 120.60 × 0.25 = Rs. 30.15

4. **Calculate the cost of Apples:**
- Price per kg = Rs. 78.40
- Quantity = 1 kg 3/4 kg = 1.75 kg
- Cost = Price per kg × Quantity
- Cost of Apples = 78.40 × 1.75 = Rs. 137.80

5. **Calculate the total cost of all fruits:**
- Total Cost = Cost of Watermelon + Cost of Cherries + Cost of Grapes + Cost of Apples
- Total Cost = 83.25 + 86.40 + 30.15 + 137.80 = Rs. 337.60

6. **Calculate the amount Reshma gets back:**
- Amount paid = Rs. 500
- Amount back = Amount paid - Total Cost
- Amount back = 500 - 337.60 = Rs. 162.40

### Final Answer:
Reshma gets back Rs. 162.40.
