Answer:
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:
2
Explanation:
any number to the power zero is 1
so 5 to the power 0 =1
3 to the power 1 is 3
1+3=4
power half represents square root
hence, square root of 4 is 2
therefore answer is 2
