I have edited the post to reduce the number of questions (I only kept the ones that were already answered) and I am creating a new post
The questions are from the test taken from the website: http://www.iq-brain.com/example/1
Bottom left. When the first two shapes are superimposed, regions that are only occupied by one shape are red, by both are white.
Bottom left. Purple\Blue is widen, turn tip black. Green is rotate, Red is turn body yellow.
Partial answer for 1:
there is a loop, pentagon, rectangle, triangle, and circle. so the answer should be to complete all the shapes. there is pentagon already given in the last one. so the missing parts are the remaining shapes. but as you can see there is 2 part is blank in the first one. so it is not possible to answer. please update the question with the missing part.
Answer for the 2:
it is C shape with hollow circle and rectangle combination. the first part is filled shape in both the option and second part is the unfilled shape and you need to combine both of them to get the answer.
