Logical Reasoning Questions and Answers

The first person shook hands with 11 remaining people, the second person also shook hands with 11 people, but we count 10, as the hand shake with the first person has already been counted. Then add 9 for the third person, 8 for the fourth one & proceeding in this fashion we get: 11 + 10 + 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 66. Hence 66 hand shakes took place before & 66 after the meeting, for a total of 132.

Four days before Monday is Thursday, simply because four days after Thursday is Monday. Besides, day after the day after tomorrow is Thursday only if present day is Monday.

6,12,1,13,5 each number in the break up signifies the corresponding letter in the alphabet. (viz. 6->f, 12->l...etc.)
Similarly 2,12,15,1,20 which signifies bloat.

D is used for F.
G is used for I.
P is used for R.
and
C is used for E. Thus, it is clear that each letter of the word FIRE stands for each corresponding letter of the coded word DGPC two places ahead. By applying the same principle, the letters QFMR will stand for SHOT. Hence, the last letter of the coded word is R.

By, comparing letters and digit, we get
T = 1
O = 2 U = 3 R = 4 C = 5 L = 6 E = 7 A = 8 S = 9 and P = 0 As the 5^thletter is SCULPTURE is P and '0' is used for P, therefore, 5th digit is the required code which is '0'.

In the given code,

PROSE = PPOQE

The first, third and fifth letters are same but in the place of second and fourth letters previous two letters are used. So,
LIGHT = LGGFT.

UMMER = RUNNER

In the given code, second, fifth and sixth letters are same. The first letter of the word (S → R) is moved one step backward, while the two middle letters (M → N and M → N) each moved one step forward to obtain the corresponding letters of the code. So,

WINTER = VIOUER.
