Let's start with a logic puzzle! Which square fits in the last grid?
What number should replace the question mark?
@DarkWolf
Theory is adding to line above = the line below
9 (9+0 = 9)
7+2 =9 (9+9 = 18)
5+7+6 = 18 (18 +7+2 = 27)
4+6+9+8 = 27
? = 9

It's a very interesting solution that does seem to technically work too. 👍It wasn't the intended answer though.
0 I think
@lazyKatz @cloudySummer
Yes, it's 0. 👍 And cloudysummer had the right explanation, you just multiply each line by 8 to get the next one.
Select the figure which satisfies the same conditions of placement of the dots as in Figure-X.
The bottom dot doesn't appear to suit 1 and 4, whilst the top dot doesn't appear to suit 3.
Therefore I think the answer is 2.
@lazyKatz
The correct answer is actually 1. This is the full explanation of why that's the case:
In fig. (X), one of the dots lies in the region common to the square and the rectangle only, another dot lies in the region common to all the four elements - the circle, the square, the triangle and the rectangle and the third dot lies in the region common to the triangle and the rectangle only. In fig. (2) there is no region common to the triangle and the rectangle only. In fig. (3) there is no region common to the square and the rectangle only. In fig. (4) there is no region common to all the four elements - the circle, the square, the triangle and the rectangle. Only fig. (1) consists of all the three types of regions.
What is the answer to the last equation?
@DarkWolf 14
@DarkWolf
Apple = 2
Banana = 2
Cherry = 3
Line 1: 2 + 2 = 4
Line 2: 2 + (2 + 2) =
6
Line 3: 2 + (3+ 3) = 8
Line 4: 2 + 2 + (3+ 3
+ 3) = 13
@Barltik2065
You found the right number for each fruit, but I think you missed the multiplication sign in the last line.
Oh I did LOL
Reading is so over rated hehe
36 ;)
@Barltik2065
Multiplication also comes before addition, so
2 + 2 x (3 + 3 + 3) =
2 + 2 x 9 =
2 + 18 = 20
Definitely tricky.
@DarkWolf
Ok... I am showing my age here ... wow
Went through foil method :(
LOL
@DarkWolf oh no, this was tricky one. Got the answer wrong twice. smh hehe
Good puzzle
@DonaldDraper
It was definitely a tricky one, I'll post the answer down below. 💡
@DarkWolf
20 🤞
Apple = 2
Banana = 2/bunch
cherry = 3 each
A + (Banana * 3 cherries) = 2 + (2*9) = 20
@VaryingCloud
Yes, that's it 👍Well done!
24
Is 36 a better try
@lazyKatz
The actual answer was 20 💡
@DarkWolf
I think you got to 36 for the same reason, If you first add 2 + 2 and multiply it by 9 after, you get to 36. But there's a rule in math that you have to multiply before you add.
2 + 2 x 9 =
2 + 18 = 20
Frank and Susan have six children: Donald, Rebecca, Michael, Faye, Solomon, and Lara. Susan is pregnant with her seventh child, a girl. Frank and Susan have chosen a name for her that fits with the other names.
The question: what will the name of the seventh child be: Jessica, Karen, Abby or Tilly?
@DarkWolf
Tilly!!!!!!! Didn’t know I had to sing for the answer lol
Nice one indeed
And I’m sure even Frank and Susan wouldn’t have thought that much xD
@DarkWolf TillyDraper and the next one would be Donald2Draper if a guy and DoraDraper if a girl
@DonaldDraper 😂
@DarkWolf
Tilly
Off the music scales
1. Do - Donald
2. Re - Rebecca
3. Mi - Michael
4. Fa - Faye
5. Sol - Solomon
6. La - Lara
7. Ti – Tilly ****
8. Do - DoraTheExplora
@Barltik2065 @VaryingCloud @cloudySummer @DonaldDraper
What is the next number in the sequence?
2 9 3 1 8 4 3 6 5 7 ?
@DarkWolf
Seriously good one
@Barltik2065
It's definitely a difficult one.
Hint: spaces have been added between some 2-digit numbers to make it harder to solve.
@DarkWolf my sis said the answer is D. It's the only one with 9 dots. 😄🐶
@richuyulin
That's the right answer for the post all the way at the top 👍 Well done by your sis. 💡
