Correct Answer: 410


Solution : Given:
12 × 9 = 810; 15 × 9 = 513

Multiply the numbers and shuffle the digits. The first digit moves to the second place, the second digit moves to the third place, and the third digit moves to the first place.
12 × 9 = 108→810
15 × 9 = 135→513
Similarly, for 13 × 8; 13 × 8 = 104→410

Hence, the second option is correct.
