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

In each diagram, multiply the numbers shown on the arms together and add the number at the very top to give a 2 digit result, written in the lower 2 spaces. So,

50 = 6 * 8 + x.
x = 2.

The average of the numbers in each column is always 4. So,

Missing Element = 4.

Using the top two grids as a source, numbers in the lower left grid equal the sums of numbers in corresponding positions of the top two grids, subtracting 1 each time, and numbers in the lower right grid equal the differences between numbers in corresponding positions of the top two grids, adding 1 each time.

Divide bigger square in four smaller square. Then,
Central Number of each smaller square = sum of the each number at Corner. So,

14 + 3 + x + 11 = 47.
x = 19.

Take any group of 5 numbers along the side of the square, and their total is always 25. So,

5 + 6 + 1 + 4 + x = x + 3 + 3 + 2 + 8 = 25.
x = 9.

In each diagram, add up the 4 outer numbers then add 2 for the left hand group, 4 for the next, then 6, then 8, and put this result in the central circle. So,

Missing Number = 7 + 3 + 5 + 6 + 8 = 29.

Calculate the sums of the numbers in the left and right hand circles, to give 2 digit answers.
Write the left hand answer in the top 2 segments of the central circle, and put the right hand answer in the bottom 2 segments of the central circle. So,
3 + 6 + 1 + 8 + 9 + 2 = 29.
4 + 4 + 3 + 2 + 7 + 1 = 21.
So,

Missing element = 21.

In each diagram, multiply the left hand number by the upper central number to give the central number one line down, and multiply the right hand number by the upper central number to give the lower central number. So,

7 * 3 = 21.
7 * 8 = 56.

As you go left to right, alternately subtract 8 to give the next number, then divide by 2.

Now,
26 is divide by 2 to give 13. So,
Missing number = 13 - 8 = 21.

Logic (Left to Right):

44 = 12 * 12 = 144 (Remove First Digit) = 144
69 = 13 * 13 = 169 (Remove First Digit) = 69
96 = 14 * 14 = 196 = 96
25 = 15 * 15 = 225 = 25
56 = 16 * 16 = 256 = 56

Similarly,
Missing Number = 17 * 17 = 289 ( Remove first digit) = 89.
