REACTION TRACKER

The starting figure we start with when we read the first statement is:

Workouts are cycling, rowing, gymnasium, jogging and boxing.

From the second and third clues (gymnasium workout is done neither on the first nor on the last day but was done earlier than rowing and jogging was done on the day immediately following the rowing day), we know that rowing and jogging should be together and also that gymnasium has to be somewhere before this.

Visuallythis can be represented as:

Fromthe fourth and sixth clues we have:

C-Rest day-B

Note'. Putting it in a box signifies that there is no break between the items in the box.

Once we have these two visual representations we can go back to our original figure and think as follows:

Since gymnasium has to precede rowing and jogging, and gymnasium is not on the first day we can have 3 possibilities for placing gymnasium—viz: Tuesday, Wednesday or Thursday.

This case is rejected because, once we place gymnasium we would need to place rowing and boxing in either Wednesday-Thursday or Thursday-Friday or Friday- Saturday. In each of these cases, we would also need to place a 3 day period having

Cycling-Rest day-Boxing. It can be easily seen that in any of these 3 situations under Possibility 1, we do not have a completely free 3 day period anywhere in the week. Thus, we can reject Possibility 1.

Possibility 2:

Thus, the answers are:

1.

(b); Tuesday is the rest day.

2. (d); 4 days

3. (d); Boxing is done on Wednesday.

4. (d); The statement in option (d) is incorrect.

5. (a); Only the statement in option (a) is correct.

Example 2

Directions: Studythe Tollowinginformationto answer these questions.

(i) Alex, Betsy, Chloe, Dennis, Edward, Fiona, Giles and Herbert are gamblers sitting around a round table facing the centre.

(ii) Dennis is the neighbour of Alex but not of Herbert.

(iii) Betsy is the neighbour of Fiona and 4th to the left of Dennis.

(iv) Edward is the neighbour OfHerbert and 3rd to the right of Fiona.

(v) Chloe is neither the neighbour of Alex nor of Giles.

1. Which of the following is wrong?

(a) Betsy is to the immediate left of Herbert.

(b) Herbert is to the immediate left of Edward.

(c) Dennis is 4th to the right of Fiona.

(d) All are correct.

2. Which of the following is correct?

(a) Dennis is to the immediate left of Giles.

(b) Alex is between Chloe and Dennis.

(c) Fiona is 3rd to the right of Dennis.

(d) Edward is between Herbert and Betsy.

3 Which of the following groups has the 2nd person sitting between the 1st and the 3rd?

(a) Alex-Fiona-Chloe

(b) Giles-Alex-Dennis

(c) Betsy-Edward-Herbert

(d) Herbert-Fiona-Betsy

4 Which of the following pairs has the 1st person sitting to the immediate right of the second?

(a) Betsy-Herbert (b) Fiona-Betsy

(c) Edwards-Giles (d) Alex-Dennis

5. Which of the following pairs are fourth to one another?

(a) Chloe-Edwards (b) Fiona-Herbert

(c) Dennis-Chloe (d) Dennis-Betsy

6. If Chloe and Giles interchange their positions, which of the following will indicate Alex’s position?

(a) To the immediate right of Giles

(b) 4th to the right of Chloe

(c) 2nd to the left of Giles

(d) To the immediate left of Chloe

6-11 :From clues (i) and (iii), we get following two possibilities:

Now, read clue (iv): Edward is third to the right of Fiona.

This information rejects Case

I. Using clue (iv), we get the following two possibilities, i.e. Case II (a) and Case II (b).

Now, from clue (ii), we come to know that Dennis is not the neighbour of Herbert.

Hence, reject Case 11(a). From clue (ii) we get the following two possibilities:

Now, Iromclue (v), Chloe can’t be the neighbour of Giles. Therefore, reject Case II (c). Again, since Chloe can’t be the neighbour of Alex, the final seating arrangement will be as follows:

The answers then become pretty straight forward

l. (c) 2. (c) 3.(b) 4.(d) 5.(d) 6.(d)

Example 3

Directions: These questions are based on the Informationthat follows.

In a row of soldiers facing North, (i) Lambert is 8th to the right of Khurusheva; (ii) Mickey is 16th from the left end; (iii) Lambert is 16th to the right of Jackson, who is 27th from the right end of the row; (iv) Khurusheva is nearer than Mickey to the right end of the row; (v) there are 5 boys between Mickey and Khurusheva.

1. How many soldiers are there between Jackson and Mickey?

(a) One (b) Two

(c) Three (d) Data inadequate

2. How far away is Khurusheva from the right end of the row?

(a) 30th (b) 10th

(c) 19th (d) 18th

3. How many soldiers are there in the row?

(a) 50 (b) 40

(c) 36 (d) Data inadequate

4. How far away is Jackson from the right end of the row?

(a) Data inadequate (b) 24th

(c) 25th (d) 27th
