For 3K to be a factor of p both 3 and k should be factors of p.
As p is the product of the integers from 1 to 30, inclusive,3 is one of the factors.
A quick glance to find out which is the highest answer choice, that falls within 1 to 30 (inclusive), gives us ---> E. 18
So the Ans is E.

Taking 1, X>0, ...................X+Y = 0 (possible),x+y<0 also possible (if y is a negative integer and y < -x Taking 2, Y<1.....................X+Y = 0 (possible if X could also be less than 0,or y = -x or X=Y=0) Taking 1 & 2, X+Y=0............... (if y = -x) There the ans is E

Ans :only (1) is sufficient to answer
k/6 + m/4 = t/12 => 2k+3m=t
divide throughout by 3 ,
(2k)/3 [ k is a multiple of 3,(2k)/3 is an integer ] + m [m is an integer] = t/3 [Integer + Integer = integer]
Therefore one of the other common factors of t and 12 greater than 1 is 3 .
