Five boys J, K, L, M and T are standing in a queue one after the other (not necessarily in the same order). There is only one boy between K and L. There are four boys behind J. T is three places ahead of L. Three of the following four pairs are alike in a certain way.
(A) TM
(B) JK
(C) KL
(D) TL
Choose the PAIRS which are alike in certain way from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A), (B) and (C) only
Step 1: Analyze the Clues
- "There are four boys behind J": In a group of five boys, if four are behind J, then J must be at the very front (Position 1).
- "T is three places ahead of L": This means there are two people between T and L.
- Possibility A: T is 1st, L is 4th (Impossible, because J is 1st).
- Possibility B: T is 2nd, L is 5th.
- "There is only one boy between K and L": Since L is in Position 5, the boy in Position 3 must be K.
- The Remaining Boy: The only position left is Position 4, which must be filled by M.
The Final Arrangement:
|
Position |
Boy |
|
1st (Front) |
J |
|
2nd |
T |
|
3rd |
K |
|
4th |
M |
|
5th (Back) |
L |
Step 2: Evaluating the Pairs
Now we check the relationship between the boys in each pair:
- (A) TM: T (2nd) and M (4th) have one boy (K) between them.
- (B) JK: J (1st) and K (3rd) have one boy (T) between them.
- (C) KL: K (3rd) and L (5th) have one boy (M) between them.
- (D) TL: T (2nd) and L (5th) have two boys (K and M) between them.
Pairs (A), (B), and (C) are alike because they all have exactly one person standing between them. Pair (D) is the odd one out.
Answer: The correct option is (A), (B) and (C) only.
