Answer: 100 3 digit even number that begin with either 5 or 6
Explanation: Case 1: A 3 digit that begin with 5 should be 500-599 so there are 100 numbers But we are only finding even number So 100/2 = 50 3-digit even number that begin with 5.
Case 2: A 3 digit that begin 6 should have 600-699 and there are also 100 number including even and odd in total. Since we are only finding even number we get: 100/2 = 50 3-digit even number that begin with 6.
Plus both case together we get 50 3-digit even number that begin with 5 + 50 3-digit even number that begin with 6= 50 + 50 = 100
