ANS. (A)
(1) IS SUFFICCIENT AS SQRT'K' IS EVENLY DIVISIBLE BY 9, ANYTHING DIVISIBLE BY NINE WILL BE DIVISIBLE BY 3

(2) IS NOT SUFFICIENT AS K^2 IS DIVISIBLE BY 3 COULD MEAN k CAN BE +VE OR -VE NOT CONCLUSIVE

I think A is wrong. Is it prohibited to divide negatives by 3?

I think (D) is Ans,

SQRT(K) divisible by 9 --> K divisible by 3 (no dispute about this)
K^2 divisible by 3, mean K*K divisible by 3, {If a*b is divisble by 3 then either of a or b should be divisible by 3) hence K is divisible by 3

D is correct. It is given in the initial question that K is an INTEGER.

(1) obvious
(2)K^2 is evenly divisible by 3, and K is an integer

K^2=3n
K has to be a multiple of 3.

hi

what does 'evenly' mean is it like 6/3 =2 which is an even integer or just that it should be some number that just is a 'multiple' of 3...

Have fun... :)
