IQ Test question watch

1. In the attached IQ test question, the correct solution is number 3.

I can see why there should be a black triangle, which narrows the solution down to 3, 5 or 7.

How is the correct solution of 3 selected from these?

2. I would imagine it's to do with the horizontal and vertical lines on each row of triangles needing to form a different sequence of colours in each row.
3. every shape has 3 elements (background triangle, horizontal line, vertical line). In each row, no colour is used twice on the same element (ie you cant have 2 black horizontal lines in the same row)

In the middle row, a black background triangle hasnt been used yet, so it should be black. Then a yellow horizontal line, and a blue vertical line, which is #3

It seems a pretty stupid question though since you only have 2 rows to make that generalisation from, and the same pattern doesnt apply to the columns
4. the three blue triangles have 2 lines. on has black and yellow, one has black and blue, one has blue and yellow. Same with the yellow triangle. The black triangle should be the same, The black triangles already have one with black and blue, and one with black and yellow, so it must be blue and yellow.
5. You could make a pretty good argument that it should be #7 actually, on the grounds that each column should use only 2 colours for each of the horizontal/vertical lines and have a unique colour for the triangle. Yeah #7 breaks the row pattern, but #3 breaks the column pattern, so its inconsistent either way.
6. row 2 needs yellow horizontal line to match pattern in rows 1 & 3
similarly column 3 needs a vertical blue line to match the pattern in the other columns... hence it has to be 3
7. It's simpler than that, there's no pattern to it really. Each element needs to appear 3 times, 3 black, blue, yellow horizontal lines, 3 black, blue, yellow vertical lines and 3 triangles of each colour. It's not about rows or columns, it's just about counting and solution 3 is the only way to have them all.
8. Its about consistency. Look at the distribution of the three shapes and the colors.
9. ChappieChappie is defiantly right on the money here.I think your confusion (and mine too) was due to the fact we saw that question on a video where Dr. Jordan Peterson talks about IQ tests. The previous two questions both had answers that relied on row and column consistency, so when this question came up next your brain was suck in that same mode and kept trying to find a complicated column/row based answer when it was, as ChappieChappie says, much simpler than that.
