Try out each answer choice
A)
45/13 = 3 remainder 6
45/6 = 7 remainder 3
45/7 = 6 remainder 3
-------------------------------------------------------
B)
58/13 = 4 remainder 6
58/6 = 9 remainder 4 <--- Remainder is NOT 3, so it can't be choice B
58/7 = 8 remainder 2 <--- Remainder is NOT 3, so it can't be choice B
-------------------------------------------------------
C)
71/13 = 5 remainder 6
71/6 = 11 remainder 5 <--- Remainder is NOT 3, so it can't be choice C
71/7 = 10 remainder 1 <--- Remainder is NOT 3, so it can't be choice C
-------------------------------------------------------
D)
84/13 = 6 remainder 6
84/6 = 14 remainder 0 <--- Remainder is NOT 3, so it can't be choice D
84/7 = 12 remainder 0 <--- Remainder is NOT 3, so it can't be choice D
-------------------------------------------------------
E)
97/13 = 7 remainder 6
97/6 = 16 remainder 1 <--- Remainder is NOT 3, so it can't be choice E
97/7 = 13 remainder 6 <--- Remainder is NOT 3, so it can't be choice E
====================================================================
So the answer is (A) 45
