Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 130
Let us arrange the numbers column-wise:
|
Top |
Middle |
Bottom |
|
5 |
48 |
8 |
|
14 |
135 |
9 |
|
12 |
? |
10 |
Pattern:
$\text{Middle} = (\text{Top} \times \text{Bottom}) + \text{Bottom}$
Check:
- $5 \times 8 + 8 = 40 + 8 = 48$
- $14 \times 9 + 9 = 126 + 9 = 135$
Apply to the third column:
$12 \times 10 + 10 = 120 + 10 = 130$
