----- explanation 1 ------
- Test case $1$: Chef has $5$ friends. The cost of buying a burger for each of them will be $10 \times 5 = 50$ while Chef has $70$ rupees. Therefore, he can buy a burger for all of them.

  • Test case $2$: Chef has $5$ friends. The cost of buying a burger for each of them will be $10 \times 5 = 50$ while Chef has $40$ rupees. Therefore, he can not buy a burger for all of them.

  • Test case $3$: Chef has $10$ friends. The cost of buying a burger for each of them will be $40 \times 10 = 400$ and Chef has $400$ rupees. Therefore, he can buy a burger for all of them.

  • Test case $4$: Chef has $14$ friends. The cost of buying a burger for each of them will be $14 \times 14 = 196$ while Chef has $150$ rupees. Therefore, he can not buy a burger for all of them.
