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

Starting with the numbers in the top two circles, add numbers in the left hand segments of each circle, and put these values in the left hand segments of the lower left circle.

Put the difference between segments in the right hand halves of the two top circles in the right hand half of the lower left circle.

Repeat this pattern for the lower right circle, but putting the difference between numbers in the left hand half of the top two circles in the left hand half of the lower right circle, and the sum of the right hand half of the top two circles in the right hand half of the lower right circle. So,

Missing Number = 6 + 2 = 8.

Starting From Bottom row,
Add numbers in adjacent boxes and put the sum in the box directly above.
So, Missing number = 16 + 17 = 33.

Reading each row as a 4 digit number, from top to bottom, rows follow the sequence of Cube Numbers from 16 to 19. So,
In the last row, there will cube of 19 i.e.
19 * 19 * 19 = 6859.
Missing Element = 9.

Split the diagram into 3 columns, each 2 spaces wide, and read each double space as a 2 digit number. Starting at the top of each column, add the 2 separate digits together, then add this to the whole 2 digit number, to give the result, written in the spaces underneath.

Working through the diagram in rows, find the difference between the left and right hand values, then add 2 to give the value in the central space. So,

Missing Element = 5 - 2 + 2 = 5.

In each square, multiply the top and bottom numbers together to give a 2 digit result, and write this result in the left and right hand spaces. So,

6 * 2 = 12.
Missing Element = 2.

Logic (Row-wise):
Central Row = Sum of the other rows. So,

4 + 5 + 8 + x = 18
x = 1.
Missing Number = 1.

Multiply the 2 numbers in the outer segments together and add 1 to give the value in the inner segment opposite. So,

Missing Number = 5 * 2 + 1 = 11.

Split each grid into 2 halves, vertically, leaving 2 columns, each 2 squares wide. Start with the top left pair and move down, then to the top right pair, and down again. Reading each pair of digits as 2 digit values, the 2 digit values increase by 11, 12, 13, 14 and 15.

In each star, the number in the centre equals the difference between the sum of the numbers in the upwards triangle and the sum of the numbers in the downward triangle. So,

For First Star,
(4 + 9 + 2 ) - (3 + 1 + 6) = 15.

Second Star,
(6 + 8 + 5) - (7 + 3 + 1) = 8.

Third Star,
( 6 + 9 + 1) - (6 + 1 + 2) = X

X = 7.
