High Level Reasoning Coded Inequalities Puzzles Practice Room

Directions (1-5): In these questions, certain symbols have been used to indicate relationships between elements as follows:
A * B means A is either equal to or greater than B.
A \$ B means A is equal to B.
A £ B means A is either equal to or smaller than B.
A & B means A is smaller than B.
A @ B means A is greater than B

In each question, three statements showing relationships have been given, which are followed by two conclusions I & II. Assuming that the given statements are true, find out which conclusion(s) is/are definitely true.
A) if only conclusion I is true.
B) if only conclusion II is true.
C) if either conclusion I or II is true.
D) if neither I nor II is true.
E) if both conclusions I and II are true.

1. Statements: S * K, T & K, K * B
Conclusions: I. S \$ B
II. S @ B

2. Statements: Y \$ Z, H \$ D, Z * D
Conclusions: I. D £ H
II. H £ Z

3. Statements: M @ N, P @ R, P & N
Conclusions: I. P £ M
II. R & N

4. Statements: T & K, K * B, S * K
Conclusions: I. B * T
II. S £ T

5. Statements: P @ R, M @ N, P & N
Conclusions: I. N @ R
II. P & M

Directions (6-10): Read carefully and answer the questions given below:
(i) Six students P, Q, R, S, T and U are in different branches of Engineering, viz. civil, mechanical, chemical, electrical, metallurgy and electronics but not necessarily in the same order.

1. Please provide written explanations for Q-1 to Q-5 as explained in session 1 & session 2

1. Sorry for delay reply here is explanation
1. S ≥ K ≥ B
S = B
S > B

2. Y = Z ≥ D = H
D ≤ H
H ≤ Z

3. M > N > P > R
P ≤ M
R < N

4. T < K ≥ B and T < K ≤ S
B ≥ T
S ≤ T

5. M > N > P > R
N > R
P > M

2. 5th got typing mistake at P < M

2. explain 5th plz.........

1. Hi Amit,
Already explained in above comment
M > N > P > R
N > R
P < M

3. can you give all the rules for "either or" case in inequality

1. Hi,
I already posted them check below
Coded Inequalities

2. Good explanation.....Thanks

3. you are welcome Priya
