Options

B. Rs 450
C. Rs 650
D. Rs 600

Explanation

To find out how much Sumit pays for getting 10 kg of clothes washed, we can break down the charges as follows:

1. **Identify the charges for the first kg of clothes**: The laundry service charges Rs. 150 for the first kg.

2. **Identify the charges for the remaining kg of clothes**: After the first kg, the charge is Rs. 50 for each additional kg. Since Sumit is washing a total of 10 kg, we need to calculate the charges for the remaining 9 kg (10 kg - 1 kg = 9 kg).

3. **Calculate the cost for the remaining kg**: The cost for the remaining 9 kg can be calculated by multiplying the number of kg by the charge per kg:
\[ \text{Cost for 9 kg} = 9 \text{ kg} \times 50 \text{ Rs/kg} = 450 \text{ Rs} \]

4. **Add the charges together**: Now, we add the charge for the first kg and the charge for the remaining 9 kg:
\[ \text{Total Cost} = \text{Cost for 1 kg} + \text{Cost for 9 kg} = 150 \text{ Rs} + 450 \text{ Rs} = 600 \text{ Rs} \]

5. **Conclusion**: Therefore, the total amount Sumit pays for getting 10 kg of clothes washed is Rs. 600.
