IMO C. But a slight different approach. Question stem is asking " X divisible by 6? " or iwe can rephrase the question as "Is x divisible by 2 and 3? " From stmt 1 - It is given x + 3 is divisbile by 3 ==> we can conclude that x is also divisible by 3. But we don't know whether x...

Intersecting the X-axis means that y = 0. This is accomplished when x is either -a or -b. So in order to solve this problem, you need to know a and b. y will also be x^2 + (a +b)x + ab. 1. a + b = -1 is not enough to find a and b, so this one is insufficient 2. this tells us that point (0, -6) is o...

Let line n be represented as y = m1x + b1 where m1 is the slope and b1 - y intercept. Let line p be represented as y = m2x + b2 where m2 is the slope and b2 - y intercept. From clue 1 it is give, that point (5,1) is the intersection ==> which means (5,1) lies on both the lines. Substitute (5,1) in t...

here is my approach. It is given 3a + 2b + c is odd. 2b will definitely be even irrespective of whether b is even or odd. For the sum(3a + 2b + c) to be odd, either of 3a or c should be odd and the other even. If c is odd, then 3a should be even making a to be even. Otherwise, if c is even then 3a s...
