2. Here is numbers: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. Split them in 5 groups. You need make groups like that, that groups have sum are ascending. For example you have 5 groups that each group has 1, 2, 3, 4, 5. (Harder version: You have numbers 0-20 and you need split them to 7 groups. Rules are same)

3.Choral music book has 700 songs that are numbered 001, 002, 003... The oldest one has bag with numbers in it. How many of each numbers are in bag, to you able to make any 4 song numbers.
(You need to say minimaliest ammount of numbers) (P.S. There is 2 answers, normal and tricky one, I will count both, so ignore it and do it kk.

4. You have 6 x 6 box with 4 X's and O's.(As you see in image) You need to split that box like that, you can fit 1 X and O in each figure AND figures are equal. You can draw lines only in lines.
Note that X and O's aren't need to be same place as other figures but they need to be in figure.
