3 1 8, 2 6 2, 4 7 5= 65 ? 54
Answers
For such questions, mentioning the options is important as there can be more than one solution.
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)

Answer:
62
Step-by-step explanation:
Add each digit in the column
1st column sum total =20
3rd column sum total = 24
2nd column sum total must be 22 (random logic)
2nd column total =1+6+7+x+y=22
X+Y=8
And among the options 62 is the right answer (x+y must equal to 8 and 6+2 is 8, xy=62)
