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

Logic:
(Sum of outer four element )/2 = Central Element.

So, Required Number,
= ( 1 + 8 + 6 + 3)/2 = 9.

First Circle:
Multiplication of to upper numbers /2 = Lower number.
= (8 * 4)/2 = 16.

Second Circle:
Multiplication of to upper numbers /3 = Lower number.
= (8 * 9)/3 = 24.

Third Circle:
Multiplication of to upper numbers /4 = Lower number.
= (12 * 9)/4 = 27.
Missing Number = 27.

Step 1
Take values in the top left and centre circles and put their sum in correspond- ing segments of the lower left circle.

Step 2
Take values in the middle and right hand circles, and put their difference into corresponding segments of the lower right circle.

Missing Number = Lower Right Segment of Middle Circle - Lower Right Segment of the Right Segment.

Missing Number = 7 - 2 = 5.

Logic:
First number + second number - 4 = Third Number.

3 +6 - 4 = 5
6 + 5 - 4 = 7
5 + 7 - 4 = 8
8 + 7 - 4 = 11
11 + 8 - 4 = 15
15 + 11 - 4 = 22.
So,
Missing number = 22.

As you move left to right, numbers follow the sequence of Square Numbers, from 36 to 121, subtracting 10 for the second number, 20 for the next, then 30 etc. So,

36
49 - 10 = 39
64 - 20 = 44
81 - 30 = 51
100 - 40 = 60
So,

121 - 50 = Missing Number
Missing Number = 71.

Logic (Column-wise):
Upper element - Middle Element = Lower element.

So,
Missing Number = 7 - 6 = 1

Logic:
(Previous Number + 1 ) * 3 = Next Number.

So,
Missing Number = (282 + 1) * 3 = 849.

Working in rows, from top to bottom, and reading each row as a 4 digit number, rows follow the sequence of Cube Numbers, from 13 to 16. So,

In the last row, there will be cube of 16.
16 * 16 * 16 = 4096.
Thus,
Missing Element = 6.

Logic (Column-wise):
Top Element + Middle Element + 1 = Bottom Element. So,

3 + 5 + 1 = 9.
2 + 2 + 1 = 5.
6 + 1 + 1 = 8.
Missing Element = 8.

Logic:

Sum of the Four Number at the corner of the square = 21 and
Sum of the Four Number at the middle of the square = 21.

Now,
7 + 5 + 6 + 3 = 21
5 + 7 + x + 8 = 21
x = 1.
Thus,
Missing Number = 1.
