Boxes and beads
We have three boxes whose contents we cannot see, and each of them contains two beads: one contains two white beads, another two black beads, and the third one black and one white bead. Each box has a label, but each one has the wrong label. What is the smallest number of beads we need to take out to find out the exact contents of each box?
Children
When asked about her children's ages, Mrs. Thomas replies that either Ana or Bill is the youngest, but Ana is only the oldest if Carl is not the youngest. Can we deduce from this which of the siblings is the oldest and which is the youngest?
Fishing
Two fathers and two sons went fishing. Each of them caught a fish, but together they only caught three. Why?
Family
Mr. and Mrs. Holt and their two children are a perfectly ordinary family. But if only two (exactly two – no more and no less) of the four statements are true, can you guess their names and who is who in the family?
- John and Leena are related.
- Bjorn is older than John.
- Diana is younger than Bjorn.

Hats
Three men are standing in a line, one behind the other, so that the last one sees the two in front of him, the one in the middle only sees the one in front of him, and the first man cannot see either of them. There are also hats: three blue and two red. Each man gets one hat to put on, and the remaining hats are placed so that none of the men can see them. All three know how many hats there are and what colors they are, but not where they are.
The last man in line claims he can't identify the color of his hat, and shortly after, the man in the middle says the same. But the man at the very front, who can't see them, recognizes the color of his hat after their answers. What color is his hat?
In the Desert
An explorer decided to cross the desert but realized it would take him six days and a single man can only carry provisions for four days. What is the minimum number of people he needs to take with him to cross the desert?
Mushrooms
Theo and Anna went into the forest to pick mushrooms. Since their mother had forbidden them to pick unknown mushrooms, they only looked for porcini and chanterelles. In total, they collected 70 mushrooms. Can we calculate how many each of them collected if we know that Anna had 4/9 of the total porcini mushrooms in her basket and Theo had 3/5 of the total chanterelle mushrooms in his basket?
Languages
This year, a fourth-grade class showed great interest in learning foreign languages. Of the 30 students, only two did not choose an additional foreign language. Of the remaining students, 14 opted for Italian and 22 for Spanish. Can you conclude from this how many students took two languages as an elective course?
