Here the logic is as follows,
9 × 8 = 72, 3 × 9 = 27, 2 × 7 = 14
⇒ 72 – 27 – 14 = 31
8 × 7 = 56, 3 × 8 = 24, 3 × 4 = 12
⇒ 56 – 24 – 12 = 20
Similarly,
7 × 9 = 63, 2 × 5 = 10, 1 × 2 = 2
⇒ 63 – 10 – 2 = 51
Hence the required number is 51.
9 × 8 = 72, 3 × 9 = 27, 2 × 7 = 14
⇒ 72 – 27 – 14 = 31
8 × 7 = 56, 3 × 8 = 24, 3 × 4 = 12
⇒ 56 – 24 – 12 = 20
Similarly,
7 × 9 = 63, 2 × 5 = 10, 1 × 2 = 2
⇒ 63 – 10 – 2 = 51
Hence the required number is 51.

The given equation is 79 - 25 - 12 = ?
To find the answer for this equation, let's analyze the given equations and their solutions:
Equation 1: 98 - 39 - 27 = 31
Equation 2: 87 - 38 - 34 = 20
In both equations, we have three numbers being subtracted from each other. Let's break down the equations further:
Equation 1:
98 - 39 = 59
59 - 27 = 32
32 + 31 = 63
Equation 2:
87 - 38 = 49
49 - 34 = 15
15 + 20 = 35
From the above breakdown, we can observe that in both equations, the first two numbers are subtracted from each other, and then the result is added to the third number. However, the final answer does not match the given solutions of 31 and 20.
Now, let's apply the same pattern to the unsolved equation:
Equation 3: 79 - 25 - 12 = ?
79 - 25 = 54
54 - 12 = 42
Therefore, the answer for the unsolved equation 79 - 25 - 12 is 42.
Hence, the correct answer is option C) 42.
