3 1 8, 2 6 2, 4 7 5= 65 ? 54
Answers
• Given:- 3 1 8, 2 6 2, 4 7 5= 65 ? 54
• To find:- 65 ? 54
•Solution:- According to the question,
In first row,
8 + 1 = 9 (3 × 3), 9 is multiple of 3.
In second row,
6 + 2 = 8 (2 × 4), & 8 is multiple of 2.
In third row,
7 + 5 = 12 (4 × 3), & 12 is multiple of 4
In forth row,
y + 54 = z (65 × 4), & here z is multiple of 65
so, 65 × 4 = 260
y = 260 - 54 = 206
So, final answer would be 206
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)
