Monday Maths Madness 21

I have more jokes this week!

Never name your son pi. Pi's a funny name isn't it? It's like if someone goes up to you and asks what your name is, you can be like 'Pi'. But then they'd say 'no, what's your full name?' You'd be all like 'Don't ask man, we'd be here forever

Sorry for the pathetic amount this week. I've been busy today, and I'm about to play Lego Batman 2 with my sister for the first time in 10 weeks, so I'm a little distracted!

Monday Maths Madness 20 - Answers

As promised, here are the answers to Monday's puzzles.

1. Christmas Past, Christmas presents

Answer: On the 12th day alone, my true loves sends to me 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78 presents.

Over the duration of the 12 days, my true love sends to me 12 partridges in a pear tree, 11 lots of 2 turtle doves, 10 lots of 3 French hens, and so on. In other words (or numbers I suppose) I get 2 x ((1 x 12) + (2 x 11) + (3 x 10) + (4 x 9) + (5 x 8) + (6 x 7)) = 364 presents. Which is one for every day of the year except Christmas!

2. What to wear where

We know that Miss Black can't be wearing the black dress, but she also can't be wearing green, as the woman in green answered her. Therefore, Miss Black is wearing white, Miss Green is wearing black and Miss White is wearing green.

3. A toast to toast

First, toast one side of slices 1 and 2. Second, toast the other side of slice 1, and the first side of slice 3. Third, toast the second side of slice 2 and 3. Then you have toasted both sides of 3 slices in just three toastings.

Well done if you got the answers :)

Monday Maths Madness 20

Today is the last Monday of my first term at university. It has gone by so quickly, but I am ready to come home at the weekend. I keep counting down the days, I can't wait! In the meantime, I have run out of pictures, so I think it's time for more puzzles. These are from Ball of Confusion again.

As I am sat here learning Christmas songs for Glee club, I feel it is appropriate to start with a Christmas puzzle.

Christmas past, Christmas presents

On the first day of Christmas my true love sent to me, a partridge in a pear tree. That was 1 present, but on the second day of Christmas, my true love sent to me, 2 turtle doves and a partridge in a pear tree. That was 3 more presents - 4 in total. We know, of course, that this continued for the entire 12 days of Christmas.

How many presents arrived on the 12th day of Christmas? How many presents arrived over the entire 12 days?

What to wear where

Three girls turned up to a party in a black dress, a green dress and a white dress. They were Miss Black, Miss Green and Miss White. Miss Black said, "It's amazing - our dresses match our names, but none of us is actually wearing the dress that matches her name."

The girl in green said "So what?".

Who was wearing which dress?

A toast to toast

You only have a grill and space for two pieces of bread under it, so it takes 4 toastings to do 3 slices on both sides. Or does it?

Can you toast 3 pieces of bread on both sides in less than 4 toastings?

That's all from me this week. I would find more, but I have songs to practise. Answers on Wednesday!
