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

Working in columns, starting with the top number, add 4 to give the next value down, and add 5 to give the one under that. So,

In Third Column:
7 + 4 = 11 and
11 + 5 = 16.
Missing element = 16.

In each star, add together the top 3 numbers, and subtract the lower 2 numbers, to give the value in the centre of each star. So,

5 + 5 + 6 - 3 -2 = x.
x = 11.

Logic (Row-wise):

Central Number = Left + Right Number + 2.
Missing Element,
6 + x + 2 = 11.
x = 11 - 8
x = 3.

Working from top to bottom, left to right, add together the first two numbers and subtract 3 to give the next value along. So,

Missing Number = 37 + 58 - 3 = 92.

Left to right, double each number and add 7 to give the next number down.

12
12 * 2 + 7= 31.
31 * 2 + 7 = 69.
69 * 2 + 7 = 145.
297 * 2 + 7 = 601.
Missing Number = 601.

The average of the outer 3 numbers is written in the centre of the star. So,

Missing Element = (9 + 11 + 7)/3 = 9.

Logic:
Lower Segment Element = Left Element + Right Element - 2

So,
6 + x - 2 = 5
x = 5 - 4
x = 1.
Missing Element = 1.

Using the numbers in the segments of the lower two circles, the numbers in the upper left circle equal the sum of the numbers in corresponding segments of the lower 2 circles, the numbers in the upper central circle equal the difference between numbers in corresponding segments of the lower 2 circles, and the numbers in the upper right circle equal the product of the numbers in corresponding segments of the lower 2 circles.

Working from left to right and reading each pair of numbers as a 2 digit value, these values represent the sequence of multiples of 7, starting at 49 and finishing on 70. So,
Missing Element = 0.

Logic (Column-wise):
Central Number = Difference of the sum of the bottom two numbers and upper two numbers.

So,
8 = (3 + 9) - (1 + x)
8 = 11 -x
x = 3.
Missing Element = 3.
