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

Starting with the 3 circles in the top row, add together values in corresponding segments of the left and right hand halves of the left hand circle, and put the results in corresponding segments of the left hand half of the central circle.

Repeat this pattern for the left and right hand segments of the right hand circle.

For the lower row, follow the same pattern, but calculating the differences between values in the left and right hand halves of the left and right hand circles, putting the results in the central circle.

Taking the top 3 numbers, add them together, and write the 2 digit result in the spaces below. Repeat this pattern for the next set of numbers. So,

9 + 9 + 2 = 20
Thus,
3 + 3 + 5 = Missing Number
Missing Number = 11.
Missing Digit = 1

Working from left to right, numbers represent the reverse alphabetical values of the vowels in the alphabet. I.e There are 5 Vowels A, E, I, O, U.

A = 1 = Reverse alphabetical number = 26.
E = 5 = 22
I = 9 = 18
O = 15 = 12
So,

U = 21 =6.
Missing Number = 6.

Working from top to bottom, and reading each pair of boxes as a 2 digit number, add 10 to the first number to give the next one down, then add 15, and 20 to complete the sequence. So,

Missing Number = 46 + 20 = 66.
Thus,
Missing Digit = 6.

As you move from left to right, the sum of the digits in each circle forms a sequence of multiples of 6, from 6 to 30. So,

2 + 1 + 3 = 6
8 + 2 + 2 = 12
9 + 6 + 3 = 18
4 + 6 + 14 = 24.
So,

11 + 6 + x = 30
x = 13.

Logic (Row-wise):
Central Element = Difference of Left and Right elements

7 - 4 = 3
6 - 2 = 4
So,
9 -3 = 6.
Missing Element = 6.

Starting on the top left, and moving clockwise around the diagram, add the first two values together to give the next value along. So,

Missing Element = 7 + 11 = 18.

For each star, add the outer numbers together and divide by 3 for the left hand, 4 for the centre, and 5 for the right hand, putting the result in the centre.

For Left Circle:
7 = ( 6 + 4 + 2 + 6 + 3)/3

Right Circle:
5 = (5 + 3 +2 + 9 +1)/4

So, for Bottom Circle,
7 = (11 + 6 +5 + 7 + X)/5
35 = 29 + x
x = 6
Missing Number = 6.

Add together numbers in corresponding segments of the upper two and lower left circles to give the values in corresponding segments of the lower right circle. So,

Missing Number = 2 +6 + 4 = 12.

Logic:

12
12 + 1 + 2 = 15
15 + 1 + 5 = 21
21 + 2 + 1 = 24
24 + 2 + 4 = 30
So,

30 + 0 + 3 = Missing Number.
Missing Number = 33.
Thus, Missing Digit = 3.
