St1] 2 k is evenly divisible by 3.
This means that k is definitely divisible by 3.
Insuff.

St2] 3 k is evenly divisible by 3.
This means that k is definitely divisible by 2
Insuff
Together we know that k has atleast one 2 and one 3 as its factors.
Hence C.
What's the OA?

Well my friend, as Sanju was trying to point out, If A is evenly Divisible by B , the remainder when A is divided by B is zero. Neither A nor B has to be Even

OA would be ---

Ok. I now figure out your point.

In terms of your understanding 'k is evenly divisible by 3' is as good as 'k is divisible by 3'

Then why would one one include the word 'evenly' in the question anyway?
It does not really play any role apart from leading one to postulate 2 different inferences.

I leave that for Sanju to Explain

Evenly divisible means leaving no remainder when divided by.

https://en.wiktionary.org/wiki/evenly_divisible

(1) obviously the statement basically states that k is an integer that is divisible by 3 (since 2k/3 is even) and that integer k cannot be smaller than 2, because if k=2, the statement wouldn't hold). 2*2/3 = not evenly divisible

Thus, k itself must be a integer that is divisible by 3, but larger than 2 for the statement to hold.

For any k that is divisible by 3, the checksum of 2k will be divisible by 3. Since 2 is prime, k itself must 'ensure' that the term 2k is divisible by 3. k can only do that if k is divisible by 3 and larger than 2. Thus sufficient.

I think it is important to understand that the statement excludes the possibility that k<3, and what it means that 2 is prime.

test:
it holds that k>2, perhaps k can be 3;6;9;12;15;...
k cannot be 1;2;4;5;7;8;10;11;13;14;...

OR

imaging fraction 2k/3 - for that to be even it must hold that k>2, and k itself is divisble by 3.

=> statement 1 is sufficient

(2) it could be that:
k=1;2;4;5 which aren't divisible by 3, but k could also be 3;6, which are divisible => so you can't say for sure whether k is divisible by 3 or not. Any integer multiplied by 3 is divisible by 3, so the statement doesn't reveal anything.

=> statement 2 is insufficient

THEREFORE: ANSWER A

i hope that helps

Once upon a time, my brother told me that I am his brother. Later, he told me that I am his real brother. This real is killing me, really. Do we have fictitious brothers too? No, no...I am if truth be told perplexed now. Why did he use real there? Doesn't he know how to-the-point kind of celebrity I am?

Thanks Sanju. I understood all of that.
This signature of yours is very insightful. I have made a small change in the part that i like best.

(1) 2 k is evenly divisible by 3.

(2) 3 k is evenly divisible by 3.

Statement 1:

2k = 3 * 2a
k = 3a
where a is any +ve integer (even or odd)

Not Sufficient

Statement 2:

3k = 3 * 2b
k = 2b
where b is any +ve integer (even or odd)

Not Sufficient

Statement 1 and 2:
k = 3a = 2b
so, k = 6c
Sufficient


Ans C

Despite the fact that it's in the interest of a reviewer to go through all the already existing posts (if any) allied to a given topic of interest before posting their original views, but it's hard for me to follow. Suggestions solicited.

Again you are missing the word 'like'.

Why aren't some like that wise old bird? is not the same as Why aren't some that wise old bird?

any FOWL?-Nah not for the OWL

OMG
that person is learning idioms in DS
the answer is def E in this case...
