In each of these questions two equations I and II are given. Based on these
Give answer if
(1) x > y
(2) x ≥ y
(3) y > x
(4) y ≥ x
(5) Either x = y or the relationship between x & y cannot be established.[1] I. y = – 5 or 4.3
II. x2 = 18[2] I. x2 + 5x + 6 = 0
II. y2 + 11y + 30 = 0[3] I. x = √64
II. y = (– 2)3[4] I. 153.5 = x
II. 57.5 = y[5] I. y – x = z
II. z *– 1 = 0.0005asked in CET(MH)

In each of the questions given below a group of digits is given followed by four combinations of letters/symbols numbered (1), (2), (3) and (4). You have to find out which of the four combinations correctly represents the group of digits based on the letter/symbol codes and the conditions given below. If none of the four combinations represents the group of digits correctly, give (5) i.e. ‘None of these’ as the answer.
Digit : 3 9 6 2 8 7 5 4 1
Letter/symbol : K T $ F H # % D M
Conditions for coding the group of digits :
1. If the first digit is odd and last digit is even, the codes for the first and the last digits are to be interchanged.
2. If the first as well as the last digit is even, both are to be coded by the code for last digit.
3. If the first as well as the last digit is odd, both are to be coded as ‘X’.[1] 564923

Seven friends M, T, K, Q, R, P & H have taken admissions in three different engineering streams Electrical, Computer and Electronics. At least two students are admitted in each stream. Each one is in a different college A, B, C, D, E, F & G. The order of students’ stream and the college is not necessarily the same. K is admitted to college C in Electronics. The one who studies in college A does not study Computers. M studies in college G but not Electrical or Computers. T & P study in the same stream but not in Electrical. H studies in college F in the same stream as K. Q studies in college B. T does not study in college E.
[1] Who studies in college ‘A’ ?
(1) T
(2) P
(3) R
(4) R or T
(5) None of these[2] Three students study in which of the following streams?
(1) Electrical
(2) Electronics
(3) Electrical or Electronics
(4) Computers
(5) Computers or Electronics[3] Which of the following combinations of student and the stream is correct?
(1) R – computers
(2) Q – Electrical
(3) T – Electrical

In the following questions the symbols @, #, $, % and * are used with following meaning as illustrated below:
‘A @ B’ means ‘A is neither greater than nor equal to B’
‘A # B’ means ‘A is neither greater than nor smaller than B’
‘A $ B’ means ‘A is not greater than B’
‘A % B’ means ‘A is not smaller than B’
‘A * B’ means ‘A is neither smaller than nor equal to B’.
Now in each of the following questions, assuming the given statements to be true, find which of the two conclusions I & II given below them is/are definitely true?
Give answer (1) if only conclusion I is true.
Give answer (2) if only conclusion II is true.
Give answer (3) if either conclusion I or II is true.
Give answer (4) if neither conclusion I nor II is true.
Give answer (5) if both the conclusions I & II are true.[1] Statements : F @ G, G $ K, K % H
Conclusions: I. G @ H
II. G % H[2] Statements : R $ M, M # N, K * N
Conclusions: I. R @ J
II. J % R[3] Statements : D % E, E @ M, M $ L
Conclusions: I. L % E
II. M * D[4] Statements : K $ V, V $ F, F * B
