For those of you enjoying the brain teasing, here is today's first challenge.

I will not post the solution until tonight, to allow those in different time zones to have a go.

Miss....Miss, please Miss it’s Doodle here at the back of the class with the dunces hat on. Please Miss I still don’t understand how you get 40 Miss.............What’d yer mean I’ve got detention ?

Marydoll Fri 03-Apr-20 21:17:58

Tomorrow's may be even trickier. I will need to word it carefully.
I have failed, a good teacher assumes nothing and makes it clear what is expected! blush

Marydoll Fri 03-Apr-20 21:14:10

^ Haud the bus, there! *Doodle please reverse back up the thread please and read the explanation I gave Callistemon.

There were only 4 lines in the puzzle! I didn't ask for the 8th line, I asked for the answer to line four.? It wasn't intended to be a sequence. It was a bit sneaky. Sorry!

Now look marydoll I’ll accept 7 sheep.
callistemon and I both got 51 days (so we get double cakes right?)
But where does the 40 come from (I’ve had a drink so explain slowly)
My logic (not two words I usually use in the same sentence ?) was 4 x 1 +1 = 5 2x5+2 =10 etc so 8x11+8 = 96
Maths not being my strong point (waiting to find out what is) please explain the 40.

Yummy cakes by the way ?

Marydoll Fri 03-Apr-20 17:15:18

No slapped wrists on my watch, other ways of punishing you! wink grin

Gemini17892 Fri 03-Apr-20 17:13:32

Not even a virtual cocktail ? ??‍?
Those buns look yummy ?????but I didn’t read the question on the first one so slapped wrist for me too. In the corner with Calli.

Marydoll Fri 03-Apr-20 17:08:36

Are you offering us a drink?

Not only am I being shielded, no alcohol allowed? sad

Gemini17892 Fri 03-Apr-20 17:06:14

I agree

Marydoll Fri 03-Apr-20 17:01:36

That's the kind of pupil I loved!

Marydoll Fri 03-Apr-20 17:00:08

Tomorrow's is going to cause all sorts of disagreements. We may need a referee! grin

Callistemon Fri 03-Apr-20 16:59:34

Thank you Marydoll

I was probably the pupil sent to stand in the corner for arguing stating my case and standing my ground

Marydoll Fri 03-Apr-20 16:48:17

Of course you can have a cake! grin You have worked so hard and argued your case so well.

The children in my class knew I was a tricky so and so and knew to read everything carefully.
Don't trust me, that's all I'm saying! wink

Callistemon Fri 03-Apr-20 16:43:16

so no cupcake then?

sad

Marydoll Fri 03-Apr-20 16:36:19

Callistemon, I know where you are coming from, but this puzzle has only 4 lines.

If it was to be a sequence, that would absolutely be correct and would have said so.
I too overthink and tend to look for more than is asked. grin
However, I never said it was a sequence. wink

Callistemon Fri 03-Apr-20 16:29:09

As I'm in an argumentative mood wink I still think 96. Because 40 seemed far too easy, I tried to look at it logically and realised that the numbers read vertically go in sequence but that some are missing, so i filled in the gaps and got 96.

1 + 4 = 5
2 + 5 = 12
3 + 6 = 21
4 + 7 = 32
5 + 8 = 45
6 + 9 = 60
7 + 10 = 77
8 + 11 = 96

Am I over-thinking these?

Marydoll Fri 03-Apr-20 16:27:18

For all those who got correct answers, well done!
For all those who didn't quite get the answer, well done too!
Here is something to go with the cuppa, littleflo, has offered to make.
The cupcakes are small, as I'm the only person who will be eating them, no visitors allowed! ?

Look out for tomorrow's session.

Callistemon Fri 03-Apr-20 16:24:30

But the sheep still belong to the farmer even if they have wandered off. They dye them to make sure whose are whose!
Unless, of course, they have been rustled and are now in someone's freezer. But even then, theoretically, they still belong to the farmer and not to the rustler. That's theft, that is.

I'll shut up now grin

Callistemon Fri 03-Apr-20 16:22:36

and Doodle grin

Callistemon Fri 03-Apr-20 16:21:21

51 days

Marydoll Fri 03-Apr-20 16:20:20

ANSWER TIME

Seven sheep. The riddle says all but seven run away, meaning there are seven left who didn’t.

It would take 51 days. If the number of flowers doubles every day, half the garden would be full the day before, on the 51st day.

Callistemon Fri 03-Apr-20 16:20:15

"The good shepherd lays down his life for the sheep.", and is probably still looking.
grin

right, I have just planted sunflower seeds but probably not enough.

Marydoll Fri 03-Apr-20 16:18:20

Lucky Four, I do have a life outside of GN, albeit a lockdown at the moment! wink ?

LuckyFour Fri 03-Apr-20 16:05:57

Definitely 96.
Lets have some more puzzles

littleflo Fri 03-Apr-20 16:02:11

Please may I have a chocolate muffin. I will make the tea.

willa45 Fri 03-Apr-20 15:43:35

Yummy!
