How many 3 digit numbers are divisible by 6 in all ? Select the correct option:
A) 149	B) 150	C) 151	D) 166	E) 172
Explanation:   Required numbers are 102, 108, 114, ... , 996   This is an A.P. in which a = 102, d = 6 and l = 996   Let the number of terms be n. Then,   a + (n - 1)d = 996   102 + (n - 1) x 6 = 996   6 x (n - 1) = 894   (n - 1) = 149   n = 150.   ANSWER IS 150
