Missing Number Finding(Reasoning Aptitude ) Questions and Answers
Explanation:-
Answer: Option B. -> 10First Method
Row-wise Logic:
First element + second element = Third Element.
6 + 9 = 15
8 + 12 = 20
4 + 6 = 10
So, required number is 10.
Second Method
Logic:
Second Row element - first row element = Result * 2 = Third Row Element.
Column 1:
8 - 6 = 2
2 *2 = 4
Column 2:
12 - 9 = 3
3 *2 = 6
Column 3:
20 - 15 = 5
5 * 2 = 10.
Required Number is 10.
Third Method:
In the First row,
6*(3/2)= 9.
6*(5/2) = 15.
In the second row,
8*(3/2) = 12.
8*(5/2) = 20.
hence,
In the third row,
missing number,
= 4*(5/2) = 10.
Explanation:-
Answer: Option B. -> 4Logic (Moving-Down):
7122 = 7 + 1 + 2 + 2 = 12.
6521 = 6 + 5 + 2 + 1 = 14.
8332 = 8 + 3 + 3 + 2 = 16.
4743 = 4 + 7 + 4 + 3 = 18.
9911 = 9 + 9 + 1 + 1 = 20.
So, sum of the last oval box = 22.
387x = 3 + 8 + 7 + x = 22.
x = 22 - 18 = 4.
Missing Element = 4.
