One inch of the pressed side of the blue pencil, measuring from its lower end, is smeared with paint.

100 light bulbs lined up in a row in a long room. Each bulb has its own switch and is currently switched off. The room has an entry door and an exit door. There are 100 people lined up outside the entry door. Each bulb is numbered consecutively from 1 to 100. So is each person. Person No. 1 enters the room, switches on every bulb, and exits. Person No. 2 enters and flips the switch on every second bulb (turning off bulbs 2, 4, 6, etc). Person No. 3 enters and flips the switch on every third bulb (changing the state on bulbs 3, 6, 9, etc). This continues until all 100 people have passed through the room. What is the final state of bulb No. 64? And how many of the light bulbs are illuminated after the 100th person has passed through the room?

While playing with a metal ring, John accidentally pushed it on his finger too far and couldn’t get it off. Trying to remove it using soap and water didn’t work. The hospital sent him to a service station thinking they could cut the metal. Since the ring was made with a specially hardened steel, it couldn’t be cut. Just then Joju arrived on the scene and suggested an easy way to remove the ring in just a few minutes. What was his solution?
