Let's start with a logic puzzle! Which square fits in the last grid?
What number should replace the question mark?
@DarkWolf 0 (everything * 8, going down)
Select the figure which satisfies the same conditions of placement of the dots as in Figure-X.
@DarkWolf I'd say 1 - dots are in following overlaps:
- triangle with rectangle only
- rectangle with square only
- all shapes at once
This seems only possible in figure 1.
Figure 2 doesn't satisfy condition 1, Figure 3 same, Figure 4 cannot satisfy conditions 2 & 3.
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
20 🤞
24
Is 36 a better try
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
@DarkWolf Tilly! (not yet an octave, though)
@DarkWolf TillyDraper and the next one would be Donald2Draper if a guy and DoraDraper if a girl
What is the next number in the sequence?
2 9 3 1 8 4 3 6 5 7 ?
@DarkWolf 2 (thanks to the 'some' in your hint)
@cloudySummer
Yes, very well done! 👍
Once the puzzle is rewritten it becomes more obvious what the answer is. There's one pattern that counts up by 1 each time, while the other one keeps doubling.
2-9-3-18-4-36-5-7?
@DarkWolf
WOW.
Totally missed that one ...
hehehehe
