Ans 5:

Class : Class 6
yes,b is the right answer. we should just turn the diamond little bit. it will become square. and the other 5 squares.

Ans 6:

Class : Class 7
5 a 5

Ans 7:

Class : Class 4
It should be 6 as the first one is the outer square(biggest one) and there are 4 small squares inside it, which makes 5 squares. There is also one square inside the figure which is tilted. It looks like a rhombus but isn't a rhombus because a rhombus doesn't have 4 angles measuring 90 degrees.

Ans 8:

Class : Class 5
Whole question is wrong. The solution is also wrong. The 'squares' in the question and the solution has to be changed to 'triangles. The only thing which was right is the diagram in the solution.

Ans 9:

Class : Class 5
B as the rhombus if turned slightly diagonally will form a square and 5 squares are already there
