The image shows a sequence of square-shaped figures containing numbers. Below the figures, there are answer options.

The problem asks to find a number (the question mark) that completes the sequence of figures. The three figures show:

1. First figure:

   • Top-left: 6
   • Top-right: 2
   • Bottom-left: 7
   • Bottom-right: 3
   • Number below the square: 167

2. Second figure (the one with the question mark):

   • Top-left: 10
   • Top-right: 4
   • Bottom-left: 5
   • Bottom-right: 4
   • Number below the square: ?

3. Third figure:

   • Top-left: 8
   • Top-right: 3
   • Bottom-left: 7
   • Bottom-right: 3
   • Number below the square: 169

The given answer choices are:

• 168
• 800
• 120
• None of these

Analysis

The numbers in the squares and the numbers below seem related to some kind of mathematical pattern, likely involving operations on the numbers within the square. Let's attempt to find the relationship:

For the first figure (6, 2, 7, 3 = 167):

• If we sum the numbers: $6 + 2 + 7 + 3 = 18$.
• This doesn't directly give 167, so the relationship may involve something more complex.

For the third figure (8, 3, 7, 3 = 169):

• The sum: $8 + 3 + 7 + 3 = 21$.

Let me calculate further to explore different possibilities.Here are the key results based on the sums and products of the numbers in each square:

1. First figure (6, 2, 7, 3 = 167):

   • Sum: $6 + 2 + 7 + 3 = 18$
   • Product: $6 \times 2 \times 7 \times 3 = 252$

2. Second figure (10, 4, 5, 4 = ?):

   • Sum: $10 + 4 + 5 + 4 = 23$
   • Product: $10 \times 4 \times 5 \times 4 = 800$

3. Third figure (8, 3, 7, 3 = 169):

   • Sum: $8 + 3 + 7 + 3 = 21$
   • Product: $8 \times 3 \times 7 \times 3 = 504$

Conclusion

For the second figure, the product of the numbers is 800, which directly matches one of the answer options. Therefore, the missing number below the second square is 800.

Would you like a deeper explanation of how the pattern works? Here are some follow-up questions to explore:

1. Could the sum of the numbers play a role in other problems?
2. How can products and sums interact in sequences like these?
3. What other operations could explain the relationship between the numbers?
4. What if a different operation (like subtraction or division) was applied?
5. How do such patterns help in reasoning for aptitude tests?

Tip: Look for relationships like sums, products, or squares in patterns involving grids of numbers!
