This is probably one of the easiest and the most scoring area in the Logical reasoning section of any aptitude-based test. Normally, questions from symbols and operations are asked in sets of 3 - 5 questions. So, you can fetch easy marks in a short span of time. Lately, this topic is gaining importance as a large number of questions in Logical Reasoning section are being asked from it.

For better understanding of this topic, some basic concepts have been explained below:

- If A = 50 and B = 60, then, is A > B? - of course not.
- If A = (50, 60) and B = (40, 50), then, is A ≥ B? - This is true, since, A is equal to B when both are 50, else A will always be greater than B.
- If A = 30 and B = 80, then, is A < B? - Of course yes.
- If A = (50, 60) and B = (40, 50), then, is A ≤ B? - This is false, as A is equal to B when both are 50, but A > B for all other values. Hence, it should be represented as A ≥ B instead of A ≤ B.
- If A = B and A > C, then, is B > C? - Of course yes.

A % B = A is greater than B. A ? B = A is either greater than or equal to B.A $ B = A is smaller than B. A # B = A is either smaller than or equal to B. A ! B = A is equal to B.

Now, for each of the questions mark your answer options as follows:

- If only conclusion I is true
- If only conclusion II is true
- If both conclusion I and II are true
- If either conclusion I or II is true
- If neither conclusion I nor II is true

I. T % U

II. M # T

I. T > U

II. M ≤ T

Hence, the **answer is option (e).**

I. Q % S

II. U $ T

I. Q > S

II. U < T

Hence, the** answer is option (c).**
