Right, think about that:

There are : A father Peter (42, his wife died) and his son John (24) and a mother Marie (42, her husband) and a daughter Sarah(24).

Imagene, the John meets Marie (not his mother ;)) and falls in love with her. They get married and on the marriage Party (@Germans: Marriage = Hochzeitsfeier, oder nich? :roll: ) Peter falls in Love with Sarah, they get married, too. After 1 year or something like that, John and Marie get a son called Horst and Peter and Sarah get a son called Phil. What realationschips would come of that?

In short:
Peter=father of John
Marie=mother of Sarah

Peter(42)+ Sarah(24)=Phil(1)
John(24) + Marie(42) =Horst(1)

1.)Peter is the Grandfather of Horst, because John is the father of Horst and Peter is the father of John

2.)Marie is the Grandmother of Phil, because Sarah is the mother of Phil and Marie is the mother of Sarah

3.) Phil is the brother of John, because Peter is the father of John and Phil

4.)Horst is the brother of Sarah, because Maríe is the mother of Sarah and Horst.

that´s normal, so far
but
5.) Because the husband of the Grandmother is always the Grandfather, John is not only Phils brother but also his Grandfather.

6.)Because the wife of the Grandfather is always the Grandma, Sarah is not only Horst´s Sister but also his Grandmother.



7)Sarah is the mother (if even not the natural one) of John, because she is the wife of his father.
Regarding to the fact, that Marie is the mother of Sarah, John is married with his own Grandmother.

8.)John is the father (if even not the natural one) of Sarah, because he is the husband of her mother.
Regarding to the fact, that Peter is the father of John, Sarah is married with her own Grandfather.

9.) 8) Implicates, that Phil is Sarahs Uncle, because he´s the son of her Husband (and Grandfather)

10) 7) Implicates, that Horst is Johns Uncle, becaus he´s the son of his wife (and Grandmother)

11) 9)+ 4) Implicate, that John is her uncle, too

12) 10)+5) Implicate, that Horst is Johns uncle.


And now it´s your turn:

Bernd(50)=father of Jens(34)
Jens(34) =father of Daniel (18)

Annette(52)= mother of Petra(34)
Petra(34) = mother of Tanja(18)

So, they meet each other and this is, what happens:


Bernd marries Petra and they get a son called Jonas
Daniel marries Annette and they get a son called Fiite
Jens marries Tanja and they get a son called Florian

What would happen?

Find the smallest number (i.e. positive decimal integer) such that if the last digit is removed and placed at the beginning to become the first digit, this new number is nine times the original one.

A hole one metre long is drilled clear through the centre of a solid sphere. What is the volume of material remaining?

the same to start with since there was no width-height-and depth of the whole that was drilled...?

@Matt
Assume the drilled hole (i.e. the removed material) is a cylinder that has a diameter greater than zero and a length of exactly one metre.

Nope the sphere is a 3D circle that is 1M radius

that said the volume would be: 41887.90204786667

But it still occupies the same amount of space, unless your talking about in a liquid...

Is the hole drilled through the center or through to the center?

How can you say it has a radius of 1m when you don't know the above?
