1. A man went to a supermarket to buy some things and asked the price of the items. The salesman answered him:
- one costs $ 1;
- eight are for $1 as well;
- thirteen are for $2;
- one hundred sixty-eight are for $3;
- four thousand nine hundred and eighty-six are for $4.

2. You are standing in front of a closed room. There is one light bulb and no windows and slits to see the light inside the room.
To the right of the door leading into the room, there are three switches that are in the “off” position, and only one of them is connected to the lamp. You need to find out which switch turns on the light. You can change the position of the switches as many times as you need, but you can enter the room only once.
1. Turn on any two switches at once, and leave the third one in the off position.
2. Wait several minutes, turn off one of the switches that have been turned on before, and enter the room. If the lamp is on, the switch that remains on is the right one.
3. If it is still dark in the room, touch the light bulb. If it is hot, a switch that was turned off before entering the room is the right one; if cold — a switch remaining off turns on the light.
