A maths puzzle for you:

Puzzle for today. OK, it's a riddle. The (nice) maths puzzles were reducing the nation's productivity:

Cindi works at our local fruit and veg shop. She is 165 cm tall, shoe size 7, and has dark hair and brown eyes. What does she weigh?

Spoiler: It's not actually a maths puzzle. It's more one of logic.

A maths puzzle to keep you amused. Everyone is more or less familiar with a chess board with its 8x8 pattern of alternating black and white squares.

The question is, how many distinct squares can be identified on a chess board? A hint is that there are 64 of the single squares and 49 2x2 squares.

And another one, although this one isn't strictly a maths one, although it does have a mathematical, or at least numerical aspect to it. It does require a bit of lateral thinking.

What are the next two letters in this sequence?

J S U N E V ...

Disclaimer:: I have not devised these myself, they come from the ABC Radio National breakfast show's Friday science puzzle segment. (The word science there is actually a hint, now I think about it.)

Well, going out from Mars, in one direction we have Jupiter, Saturn, Uranus, and Neptune, and in the other direction Earth, Venus and Mercury, so maybe M?

pardon the pun, but that should be the sum of the squares from 1 to 8:  1+4+9+16+25+36+49+64 = 204

Precisely! As they read it out I was contemplating working it out by brute force but when they gave the clue about 2x2 the penny dropped.
