Missing Number Finding - General Inteligence & Reasoning MCQ Questions and Answers

In each slice of the circle, the difference between the outer and middle numbers is written in the inner segment of the opposite slice. So,

Missing Element = 4 - 2 = 2.

Calculate the difference between adjacent numbers in the centre of each oval and put the result in the space between the two ovals in the opposite side of the diagram. So,

x - 1 = 3
x = 4.
Missing element = 4

Numbers in the top right hand grid equal the sum of the numbers in corresponding positions in the upper and lower left hand grids, and numbers in the lower right hand grid equal the difference between numbers in corresponding positions in the upper and lower left hand grids.

Logic:
Central Number = Difference of the sum of number in left Column and numbers in right column. So,

Missing Element = (4 + 2 + 6) - (1 + 3 +2) = 6.

In each diagram, the number at the top equals the average of the four lower numbers. So,
9 = (8 + 3 + 11 +x )/4
9 * 4 = 22 + x
x = 36 - 22 = 14.
Missing Element = 14.

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.

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.

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

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.

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.
