↧↧↧ Detailed Video Solution to the Problem Series ↧↧↧



n is divisible by 14 and 3

=> n = LCM(3,14)*k (where k is an integer) = 42k [Watch this video to MASTER LCM and GCD]

I. 12 is a factor of n.
n = 42k = 6*7k
Now, 12 will be a factor of n ONLY when k is even, which might not be true always
=> FALSE for MUST be true

II. 21 is a factor of n.
n = 42k = 21*2k
=> 21 is a factor of n
=> TRUE

III. n is a multiple of 42.
n = 42k
=> n is a multiple of 42
=> TRUE

So, Answer will be B, C
Hope it helps!
