Logical Reasoning & Analytical Ability

Directions for the following 3 (three) items:

Consider the given information and answer the three (3) items that follow.

Four friends P, Q, R and S, each having 100 gold coins at the start, begin to play a game having 10 rounds. At the end of every round, one of them loses and, as result, has to give away 5 gold coins each to the other three. The first three rounds were lost by P followed by lose of a round by S. Next round was lost by R followed by lose of 2 successive rounds by Q. P lost the next round followed by a lose by S. The last round was lost by R.

Directions for the following 5 (five) items :

Consider the given information and answer the five (5) items that follow.

J, K, L, M and N are five boys in a class. They are ranked in order of heights – from the tallest to the shortest – and in order of cleverness – from the cleverest to the dullest.

K is taller than N, but not as clever as J and L, whereas M is the cleverest of all but shorter than J. While L is shorter than M but taller than K, L is not as clever as J. No two boys got the same ranks in any of these parameters.

#6. Who is the third in the order of heights?

(a) J

(b) N

(c) K

(d) L

#7. If N is not the last in at least one of the two comparisons, who of the following is the dullest of all the five?

(a) K

(b) L

(c) M

(d) J

#8. If L is the third in order of cleverness, who is the dullest of all?

(a) L or M

(b) J or K

(c) M or N

(d) N or K

#9. Who among the following is cleverer as well as taller than K?

(a) L and J

(b) N

(c) L and N

(d) J, L and M

#10. How many boys are definitely shorter than K?

(a) 1

(b) 2

(c) 3

(d) 0

Solutions:

Ans 1 – 3 :

Ans 1 (a) :

Ans 2 (b) :

Ans 3 (d) :

Ans 4: (d)
All books are good. All good books are read. This simply means all books are read.

Ans 5 (b) :
A does not play Baseball or Cricket.
B does not play Kabaddi or Volleyball.
C plays Volleyball.
D plays Baseball or Volleball.
From above we can conclude, Cricket is not played by A or C or D. Hence B plays cricket.

Ans 6 to 10:

Conditions for Heights

K > N
J > M
M > L > K
Using the above three conditions we got the final order of heights as under:
J > M > L > K > N

Conditions for ‘Cleverness’

J and L > K
M is cleverest
J > L
Using the above three conditions we know that: M > J > L > K
Now depending upon position of N we can have following situations:
(1) M > N > J > L > K
(2) M > J > N > L > K
(3) M > J > L >N > K
(4) M > J > L > K > N

Ans 6 (d) :
Third in order of height is L.

Ans 7 (a) :
N is not the last in at least one of the comparison. But we know for sure that N is last in heights, that means N is not the last in cleverness. That means out of four possible conditions for cleverness that we worked out, (4) is not possible and looking at other three we know that K is dullest.

Ans 8 (d) :
If L is third in cleverness then possible situations are (3) and (4) and hence either N or K is dullest.

Ans 9 (d) :
Taller than K = J, M and L and clever than K = J, L and M (will not consider N of (4) case because he is shorter than K)

Ans 10 (a) : Only N is shorter than K.
