Explanation: A two-digit number higher than 9 and a multiple of 51 should be 51 itself, according to assertion .Because 2 x 51 equals 102. (3 digit number). As a result, I am sufficient to respond. Statement II: A two-digit number larger than 9 with a six-digit total. 15, 24, 33, 42, and 51 are all possibilities. As a result, we can't deduce the needed answer only from assertion II. As a result, I alone provide the solution, but II alone is insufficient to provide an answer.
