Solution

✅ Correct Option: 2

The rule is that the product of the two top numbers and the bottom vertex, divided by 1010, gives the remaining entry.

Triangle 1: 5×6×410=12\frac{5 \times 6 \times 4}{10} = 12.

Triangle 2: 4×8×1010=32\frac{4 \times 8 \times 10}{10} = 32.

Triangle 3: 6×7×510=21010=21\frac{6 \times 7 \times 5}{10} = \frac{210}{10} = 21.
