A network of 20 x 10 squares is given to you.

I welcome the day with a show of light, I stealthily came here in the night. I bathe the earthy stuff at dawn, But by noon, alas! I'm gone.

Take 9 from 6, 10 from 9, 50 from 40, and leave 6.

How Come ??

In a kingdom, King George did not allow any citizen to visit the world outside. Also, only a person with proper paperwork was allowed to enter or he was sent back. A wooden bridge was what connected the kingdom to the world. The king had appointed a sharpshooter who would check the every five minutes on the bridge to check. After checking, he would go back to his hut and return exactly after five minutes again. The bridge took 9 minutes to cross.

A merchant was able to escape the kingdom without harming the shooter. How?

I have a hole in my back and legs I lack.
I live where I can’t breathe and I eat without teeth.
What am I?

What has one eye, but can’t see?

What country can make you shiver?
