Answers
Given :
3 1 8
2 6 2
4 7 5
65 ? 54
We have to find the value of missing number (?) is:
Solution:
The pattern follow(row wise):
In first row:
8 + 1 = 9, multiple of 3.
In second row:
6 + 2 = 8, multiple of 2.
In third row:
7 + 5 = 12, multiple of 4.
In fourth row :
54 + ? = multiple of 65, which will be nearest to
? = 130 - 54
⇒ ? = 76
∴ Missing number (?) = 76
Thus, there is no option matched.
Given data:
3 1 8
2 6 2
4 7 5
65 ? 54
Options:
(1) 60
(2) 58
(3) 68
(4) 62
To find:
The missing number.
Solution:
By option verification.
In each column, the sum of singled digits of each row goes in the series 20, 22, 24,...
We need to find the option that satisfies the total to get 22.
Column 1: 3 + 2 + 4 + (6 + 5) = 20
Column 2: 1 + 6 + 7 + (x + y) = 22
Column 3: 8 + 2 + 5 + (5+4) = 24
From column 2,
1 + 6 + 7 + (x + y) = 22
14 + (x + y) = 22
(x + y) = 22 - 14
(x + y) = 8
By option verification, find which value on adding their individual digits gives 8 as a sum.
Option 1: 60 = 6+0 = 6 which is not equal to 8 (incorrect)
Option 2: 58 = 5+8 = 13 which is not equal to 8 (incorrect)
Option 3: 68 = 6+8 = 14 which is not equal to 8 (incorrect)
Option 4: 62 = 6+2 = 8 which is EQUAL to 8 (CORRECT)
Therefore, the missing value is 62 (Option 4)
