Find the right combination
The computer chose a secret code (sequence of 4 digits from 1 to 6). Your goal is to find that code. Black circles indicate the number of hits on the right spot. White circles indicate the number of hits on the wrong spot. Calculate the number 824
NUMBERMANIA: Calculate the number 824 using numbers [2, 6, 3, 5, 61, 942] and basic arithmetic operations (+, -, *, /). Each of the numbers can be used only once. MAGIC SQUARE: Calculate A-B-C
The aim is to place the some numbers from the list (4, 7, 10, 14, 15, 17, 18, 20, 21, 85, 87) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B-C. 
The Post Turtle
While suturing up a cut on the hand of a 75 year old farmer, whose hand had been caught in the gate while working his cattle, the doctor struck up a conversation with the old man. Eventually the topic got around to Hone Hawariwa and how he got to be an MP.
The old farmer said, "Well, ya know, Hone is just a Post Tortoise."
Now not being familiar with the term, the doctor asked,
What's a "Post Tortoise?"
The old farmer said, "When you're driving down a country road and you come across a fence post with a Tortoise balanced on top, that's a post Tortoise."
The old farmer saw the puzzled look on the doctor's face so he continued to explain. "You know he didn't get up there by himself, he doesn't belong up there, he doesn't know what to do while he's up there, he sure as hell isn't goin' anywhere, and you just wonder what prick put him there in the first place."
