Agree with the point above. As pointed out, we can arrive at a+b>=7. So C is not incorrect. But this also means by default that a+b is greater than or equal to 5 (or 6).

If a+b>=7 then shouldn’t a+b>=5 and 6 also be true?
in my opinion, it cannot be option A or B because the answer is a+b= 5+ any even value for a (2,4,...). The equal to sign is also there hence the total should be as an answer, but in this case a+b cannot be 5 or 6 and the least possible value is 7 so option C.

My take - >= Means greater than OR equal to. Because a+b>=7, a+b >6 is a true statement. If a+b is 7 or above, then, by default, it is greater than 6. The condition "greater than or equal to" is satisfied because a+b is definitely greater than 6. The "or" in greater than or equal to means either of the two conditions, greater than, or equal to, must be satisfied. Here, the "greater" condition is satisfied. I am not sure one can say A and B are incorrect. Though of course, C is clearly correct.

So you’re saying 7>=5 is not true?

a+b>=7, if we take any other option like 1st or 2nd, then a+b=5 or a+b=6 wont hold true for any value of a&b. Hence they must be rejected!

@Piscine15, can we say since a + b = 8 won’t hold true for any value of a & b, so a+b>=7? So do we reject it? :)

I agree with HarshR9

See two conditions have to be met! 1.) a+b = (some value) & 2.) a+b> (some value).... a+b>(some value) holds true for option a, b and c. However, the 1st condition i.e. a+b = (some value) true only for option C.

Hence, C must be a correct choice.

You are absolutely correct in saying that C "must" be a correct choice because the value of "a+b" is a subset of the inequality shown in choice C. But at the same time choice A & B are also correct, since the stem asks us about "which inequalities hold true" going by the definition, the values taken by "a+b" are also a subset of choice A & B. And I say subset because a+b>7 means that a+b can also be 7.0000001,7.000002 and so on, but since we know that a & b are integers we are ignoring such possibilities.

It’s maths and we can agree to disagree as well!

is-it-true-that-point-j-k-lies-on-the-line-given-by-the-equation-y-365100.html

can anyone pls help with this question ?
I marked B as it gave me a definite answer that k != 3j + 11
from A, it could be said that k can or can’t be 3j + 11

see when 2 multiplication of 2 func is 0, it can be any one of them or both of them could be zero. Now if you take a case in which the second expression in both the statements is zero after combining the two statements, there can be manu solutions which satisfy 8j+2k+23=0 but not the two equations as they can be not equal to zero. hence identification of values of j&k and ascertaining if they lie on the line is not possible

yes I understand your point. but if we take statement 2, irrespective of whether we take function 1 to be 0, function 2 to be 0 or both of them to be 0, we get a definitive answer that (j,k) can’t lie on the line y = 3x + 11. why then is B not the answer ?

Let’s say j = -11/3 and k = 0
This satisfy the given equation in statement 2 and also satisfy the equation of line, but for other values of j and k,equation in statement 2 can be satisfied but the equation of line cannot. So no definite answer. Hence B is not sufficient.
