A sales representative plans to visit each of six companies M, N, P, Q, R and S exactly once during the course of one day. She is setting up her schedule for the day according to the following conditions :
(i). She must visit M before N and R.
(ii). She must visit N before Q.
(iii). The third company she visits must be P.
The sales representative could visit any of the following companies immediately after P except :
Answer: E
Correct answer: M
The company immediately after P is the fourth. M must precede N and R, and N must precede Q, so three visits have to come after M. With M fourth only two places remain, which is not enough. Every other company can be placed fourth in some valid schedule, so M is the exception.

If the sales representative visits Q immediately before R and immediately after S, she must visit Q
Answer: D
Correct answer: Fifth
The three visits S, Q, R must be consecutive, and they cannot include the third place, which is reserved for P. The only run of three consecutive places avoiding it is the fourth, fifth and sixth, so S is fourth, Q fifth and R sixth. That leaves M and N for the first two places, in that order since M precedes N.

Which of the following could be the order in which the sales representative visits the six companies ?
Answer: A
Correct answer: M, S, P, N, R, Q
Check the three conditions against each option. The third company must be P, which rules out three of the five at once. Of the two beginning correctly, Q, N, P, R, S, M places M last although M must come before N and R. M, S, P, N, R, Q satisfies every condition: P is third, M precedes both N and R, and N precedes Q.

A * B means A and B are of the same age;
A - B means B is younger than A;
A + B means A is younger than B;
Sachin * Madan - Reena means
Answer: A
Correct answer: Reena is the youngest
Read the two symbols in turn. Sachin * Madan means the two are of the same age. Madan − Reena means Reena is younger than Madan. Since Sachin equals Madan and Reena is below Madan, Reena is below both - the youngest of the three.

X + Y + Z is same as toX + Y + Z is same as to
Answer: B
Correct answer: Z-Y-X
X + Y means X is younger than Y, and Y + Z means Y is younger than Z, so the ages run \( X < Y < Z \). Now read Z − Y − X: the first says Y is younger than Z, the second that X is younger than Y. That is the same ordering expressed with the other symbol, so the two statements are equivalent.

Deven - Shashi * Hemant is opposite to
(i). Hemant + Shashi + Deven
(ii). Hemant - Shashi + Deven
(iii). Shashi * Hemant + Deven
Answer: D
Deven - Shashi * Hemant means Shashi is younger than Deven, and Shashi and Hemant are of the same age. Thus, Deven is the oldest. Now, the opposite statement would mean : Deven is the youngest.
(i). Hemant + Shashi + Deven means Hemant is younger than Shashi, who is younger then Deven. So, Deven is the oldest.
(ii). Hemant - Shashi + Deven means Shashi is younger than both Hemant and Deven. Thus, either Hemant or Deven is the oldest, but Deven is not the youngest.
(iii). Shashi * Hemant + Deven means Shashi and Hemant are of the same age and Hemant is younger than Deven. So, Deven is the oldest.

At the end of a cricket series, when five players were arranged iin the ascending order of runs scored by them, O was fourth while N was first. When they were arranged in descending order for wickets taken by them, K replaces O while O replaces L. M's position remains unchanged. K has scored more runs than M. L is having first rank in ine ranking and fifth in another.
Who has scored the highest runs in the series ?
Answer: B
In terms of runs scored, we have the ascending order as N < ? < ? < O < ?.
N has the first rank. So, L will be fifth in this order i.e. N < ? < ? < O < L.
K has scored more runs than M i.e. K > M.
So, the sequence becomes N < M < K < O < L.
In terms of wickets taken, the order becomes : L > M > N > K > O.
L has scored the highest runs in the series.
