Study the table given carefully and choose the correct number option that shall come in place of '?':

51412
48135?
8910

Solution

✅ Correct Option: 1

Looking at the table, we need to identify the pattern connecting the three rows in each column.

51412
48135?
8910

Analyzing Column 1:

Top = 5, Bottom = 8, Middle = 48

Testing: 5×8=405 \times 8 = 40

The difference is 48−40=848 - 40 = 8 (which equals the bottom number)

So: 5×8+8=485 \times 8 + 8 = 48 ✓

This can be written as: Middle == Bottom ×\times (Top +1+ 1)

Middle =8×(5+1)=8×6=48= 8 \times (5 + 1) = 8 \times 6 = 48 ✓


Verifying with Column 2:

Top = 14, Bottom = 9, Middle = 135

Middle =9×(14+1)=9×15=135= 9 \times (14 + 1) = 9 \times 15 = 135 ✓


Applying the pattern to Column 3:

Top = 12, Bottom = 10, Middle = ?

Middle =10×(12+1)= 10 \times (12 + 1)

Middle =10×13= 10 \times 13

Middle =130= 130

Therefore, the answer is Option 1: 130.
