Answer: Option A. -> 6
Calculating the sum of the 3 numbers in each row, from top to bottom, the rows follow the sequence of 11, 13, 15 etc. i.e.
3 + 5 + 3 = 11
2 + 4 + 7 = 13
8 + 4 + 3 = 15
6 + 2 + 9 = 17
So,
2 + 11 + x = 19
x = 6.
Missing Element = 6.

Answer: Option B. -> 6
Start with the numbers along the top right diagonal of the diagram, and add pairs of adjacent numbers together, putting the result in the square to the lower left of the original pair of numbers. Continue in this way towards the lower left hand corner. I.e
4 + 2 = 6
2 + 1 = 3
6 + 3 = 9
So,
1 + x = 7
x = 6

Answer: Option D. -> 14
Add together numbers in corresponding segments of the upper 2 squares, and put the results in the middle square. Numbers in the lower left square equal the product of the upper left and central squares, and numbers in the lower right square equal the product of the upper right and central squares.

Answer: Option A. -> 9
Taking numbers in diagonally opposite squares, calculate their sum, and put the answer in the small, inner square of the upper number. Calculate their difference, and put this answer in the small, inner square of the lower number. So,
3 + x = 12
x = 9.
Or.
x - 3 = 6
x = 9.
Missing Element = 9.

Answer: Option C. -> 5
Start with the row of 4 numbers in the centre of the diagram, and add adjacent pairs of numbers together, putting the results in the circles directly above. Repeat this pattern for the next row up. Next, calculate the difference between adjacent numbers in the middle row, putting the results in the circles directly below. Repeat this pattern for the next row down.

Answer: Option D. -> 43
Logic:
Central Number = Multiplication of lower numbers + upper number
So,
Missing Number = 5 * 8 + 3 = 43.
Logic:
Central Number = Multiplication of lower numbers + upper number
So,
Missing Number = 5 * 8 + 3 = 43.
Answer: Option A. -> 37
72
72 - 3 = 69
69 - 5 = 64
64 - 7 = 57
57 - 9 = 48.
48 - 11 = 37
So, Missing Element = 37.
72
72 - 3 = 69
69 - 5 = 64
64 - 7 = 57
57 - 9 = 48.
48 - 11 = 37
So, Missing Element = 37.
Answer: Option C. -> 10
The numbers on the points of the lower triangle equal the sum of the numbers on corresponding points of the upper two triangles. So,
Missing number = 6 + 4 = 10.
The numbers on the points of the lower triangle equal the sum of the numbers on corresponding points of the upper two triangles. So,
Missing number = 6 + 4 = 10.
Answer: Option A. -> 6
Numbers in the segments of the lower left circle equal the sum of the numbers in the upper left and central circles. Numbers in the segments of the lower right circle equal the sum of the numbers in corresponding segments of the upper right and central circles.
Numbers in the segments of the lower left circle equal the sum of the numbers in the upper left and central circles. Numbers in the segments of the lower right circle equal the sum of the numbers in corresponding segments of the upper right and central circles.
