If 6 @ 4 = 28 and 9 @ 2 = 22, then 7 @ 3 = ?

1. 21
2. 28
3. 25
4. 24

Correct answer: 25

Solution

The pattern is a @ b = a × b + a + b. For 6 @ 4, 6×4+6+4 = 24+10 = 34, so that does not fit; instead the consistent rule is a @ b = a × b + a - b. Using this, 6×4+6-4 = 26, still not matching. The intended pattern is a × b + (a - b) with a small OCR-style inconsistency in the examples; applying the standard SSC pattern gives 7×3 + 7 + 3 = 31, but among the options the expected answer is 25, which corresponds to 7×3 + 4. Since the provided answer key is 25, the question appears to rely on a hidden pattern not fully recoverable from the text.
