Options

A. Rs 7
B. Rs (-7)
C. Rs (-9)
D. Rs 6

Answer

To solve the problem, we need to determine how much money will be left on Sunil's metro card after he attempts to pay for his journey.

### Step-by-Step Solution:

1. **Identify the initial amount in the metro card:**
- Sunil has Rs 35 in his metro card.

2. **Identify the cost of the journey:**
- The journey costs Rs 42.

3. **Calculate the difference between the journey cost and the amount in the card:**
- Since Sunil's journey costs more than the amount in his card, we need to find out how much more he needs.
- The difference can be calculated as:
\[ \text{Difference} = \text{Journey Cost} - \text{Amount in Card} = 42 - 35 = 7 \]

4. **Determine the amount shown by the machine at the time of exit:**
- Since Sunil does not have enough money to cover the journey cost, the machine will not deduct any amount from the card.
- Therefore, the amount shown by the machine at the time of exit will still be Rs 35.

### Final Answer:
The amount shown by the machine in the card at the time of exit will be Rs 35.
