9 + 3 + 5 + 4 + 2 + 1 = 24.
625 = 6 + 2 + 5 = 13.
24 * 13 = 312 = 3 + 1 + 2 = 6.
Opt B = 5 + 8 + 4 + 6 + 3 + 8 +1 + 2 + 5 = 42 = 4 + 2 = 6.
Hence, Option B is the answer.
625 = 6 + 2 + 5 = 13.
24 * 13 = 312 = 3 + 1 + 2 = 6.
Opt B = 5 + 8 + 4 + 6 + 3 + 8 +1 + 2 + 5 = 42 = 4 + 2 = 6.
Hence, Option B is the answer.
