[4meonly]

If k is a positive integer, does k have more than 3 different prime factors?
(1) k < 200
(2) k > 100

OA after some discussion – I doubt whether OA is correct.

i go with A.

statement 1. K<200

none of the numbers below 200 have 4 different prime numbers ( 2*3*5*7 = 210>200) .. hence sufficient. it tell us none of the numbers <200 have more than 3 different prime factor.

Statement 2 . K> 100 .. insuffcient ..if k =210 then it has 4 different prime factors..

Thus A.

Hope it helps...
