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

Logic (Clock-wise):
Sum of the outer element of the triangle = Central digit of next triangle.
So,
Sum of the outer digit of the Second triangle = Central digit of the third triangle.

x = 8 + 1 + 0
x = 9.
So, Missing Number = 9.

First Number = Square of 1 * 2 = 2.
Second Number = Square of 2 * 2 = 2 *2 * 2 = 8.
Third Number = Square of 3 * 2 = 9 * 2 = 18.
Fourth Number = Square of 4 * 2 = 16 * 2 = 32.
Fifth Number = Square of 5 * 2 = 25 * 2 = 50.
So,
Missing number = Square of 6 * 2 = 36 * 2 = 72.

Logic:
Next Number = Previous Number *2 - 4.
Missing number = 36 *2 - 4 = 72 - 4 = 68.

The sum of the numbers along each side of the triangle is always 11.
So,
x + 2 + 5 = 11.
x = 11 - 7 = 4.

Left to Right, numbers increase by 3, then 2, then 1 after this it will start repeating the pattern.
5 + 3 = 8.
8 +2 = 10.
10 + 1 = 11.
Now, pattern will repeat.
11 + 3 = 14.
14 + 2 = 16.
So, Missing number = 16.

Logic (Row-wise):
Sum of each Row element = 18.

So,
18 = 0 + 6 + 5 + x.
x = 7.
Missing number = 7.

The sum of the 4 digits at the corners of the diagram is 17, as is the sum of the 4 digits in the middle of each side of the diagram.
So,
17 = x + 8 + 4 + 3.
x = 2.
Missing Number = 2.

Clock-wise:
First Square:
2 + 3 + 6 + 9 = 20.

Second Square:
6 + 7 + 3 + 3 = 19

Fourth Square:
6 + 9 + 1 + 1 = 17

Third Square:
1 + 3 + x + 5 = 18
x = 18 - 9 = 9.
Missing Number = 9.

Logic:
Third number = Sum of previous two numbers - 3.

So,
x = 29 + 45 - 3 = 71.
Missing number = 71

7 - 3 = 4.
9 - 3 = 6.
So,
12 - 3 = 9.
