This bilingual Missing Number item asks the learner to solve “Solve this Missing Number question: Find the missing number: Row 1: 5, 7, 47; Row 2: 9, 4, 49; Row 3: 10, 6, ?” through a complete, auditable missing-number relation.

A76

B77

C75

D82

Correct Answer: 76Your Answer: A

Explanation

The question-specific working supplied with the item states: The same positional rule must explain every row. Verification of Row 1: (5 × 7) + 5 + 7 = 47, exactly matching the given result. Verification of Row 2: (9 × 4) + 9 + 4 = 49, again matching the stated result, so the rule is consistent rather than a guess. Apply it unchanged to Row 3: (10 × 6) + 10 + 6 = 76. A valid missing-number solution cannot switch operations only for the final row. Rechecking the first two examples and then independently recalculating the target row confirms the answer. This working identifies the relevant missing-number relation and connects the given information to the required result. A plausible-looking option is not sufficient unless it reproduces the complete missing-number relation.

What is the verified answer to “Solve this Missing Number question: Find the missing number: Row 1: 5, 7, 47; Row 2: 9, 4, 49; Row 3: 10, 6, ?”?

76, option A.

Which method solves this Missing Number item?

Rebuild and verify the complete missing-number relation.

Why are the other options incorrect?

77, 75, 82 break a clue, direction, transition or operation.

How should the answer be checked?

Replay the rule from the first clue or term and test every intermediate step.

What is a Missing Number question in reasoning?

A Missing Number question presents related numbers in rows, columns or groups and hides one value. The solver identifies a single arithmetic rule that fits every complete example and applies it unchanged to calculate the missing value.

How do I solve Missing Number puzzles quickly?

Check simple addition, subtraction, multiplication and division first. Then test squares and mixed operations. Verify the proposed rule on every complete row before calculating the missing row, and finally eliminate options by exact arithmetic.
