Answer: A A: The numbers of multiples of 3 between 102 and 729: We should find the minimum and maximum multiples of 3 in this range of numbers. 102 is a multiple of 3 and the maximum multiple of 3 in this range is 729. Multiples of 3: 102, 105, 108, …., 720, 723, 726, 729 How many numbers are there in this sequence? (Max - min)/ distance +1 = (729 - 102) / 3 + 1 As we see A is 1 value bigger than B and is the answer. _________________
