The below figure consists of a rectangle and the numbers labeled over the top represents the area of that particular shaded region.
Calculate the area of the green region labeled as '?'
The White triangle is similar to the Red triangle
As ratio of areas = ratio of bases when height is same,
Ratio of sides is 2:3
White triangle = 9/4 * Red triangle = 9/2
Thus the Green Region = 5.5 units.
You are given 16 witch hats. The hats are divided in four different colors – red, blue, green and yellow. Every color has been assigned to four hats. Now each of the hat will be glued with a label of an arithmetic sign – ‘+’, ‘-‘, ‘x’ or ‘/’. But you can label one sign only once on one color. In such an arrangement, the hats can be uniquely defined by its color and symbol.
Can you arrange all the 16 hats in a 4x4 grid in a fashion that no two rows and columns have a repetition of color or sign?
We have arranged four hats in the below picture to assist you.

Can you count the number of matches in the picture below ?
8
This can be a really tricky question. The five matches in the front are clear. Now a part of what you see on the lighter are reflection. There are five matches in total that are part of the reflection. Out of those five, we can see that three are visible apart from the reflection as well. So the total becomes eight.
