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.

I’m stumped here Marydoll and far even picture the sum confused

GracesGran that is brilliant! ?

7 sheep

Sheeps still sheeping presumably so 19 although it might take a while to find them. If the runaways got killed (hit by passing car or lightening or stolen by a neighbour) then he has 7. If he is a good Christian shepherd then he knows:

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

Gemini, I love it!
Thanks all for joining in the spirit of things.

Here is another to keep you going, I still haven't made that cake yet! sad

You planted sunflower ? seeds in your back garden. Every day, the number of flowers doubles. If it takes 52 days for the flowers to fill the garden, how many days would it take for them to fill half the garden?

gillybob Fri 03-Apr-20 10:43:17

Or 19 if he rounds them up quick !

gillybob Fri 03-Apr-20 10:42:52

Eh? 7? ?

Callistemon Fri 03-Apr-20 10:42:36

19

Marydoll Fri 03-Apr-20 10:40:54

A wee quickie to keep you going.

A farmer has 19 sheep on his land. One day, a big storm hits and all but seven run away. How many sheep does the farmer have left?

Marydoll Fri 03-Apr-20 10:40:01

They are alll + signs.
No working please, at taht spols it for those who may want to try.

I will post the answer tonight to allow wila, who is the USA in lockdown to have a go!

gillybob Fri 03-Apr-20 10:36:52

Assuming it’s a + sign ? In which case I stick with 40.

If it’s a x sign (it’s hard to make out on my phone) then 96.

Callistemon Fri 03-Apr-20 10:08:28

Oh, cake for all of us?

Grany Fri 03-Apr-20 10:08:12

I think 40 too

Callistemon Fri 03-Apr-20 10:08:05

But I will try now to fathom how other posters got a different answer!
