### Explanation:

Test case $1$: The car runs for $800$ kms. Thus, he needs to pay $800\cdot 10 = 8000$ rupees.

Test case $2$: The car runs for $3$ kms. However, since Chef booked the car for whole day, he needs to pay for at least $300$ kms. Thus, he needs to pay $300\cdot 10 = 3000$ rupees.

Test case $3$: The car runs for $299$ kms. However, since Chef booked the car for whole day, he needs to pay for at least $300$ kms. Thus, he needs to pay $300\cdot 10 = 3000$ rupees.

Test case $4$: The car runs for $301$ kms. Thus, he needs to pay $301\cdot 10 = 3010$ rupees.

Test case $5$: The car runs for $300$ kms. Thus, he needs to pay $300\cdot 10 = 3000$ rupees.
