If ‘KCLFTSB’ stands for ‘best of luck’ and ‘SHSWDG’ stands for ‘good wishes’, which of the following indicates ‘ace the exam’?
MXHTC
This question is a classic example of a coding-decoding problem, where a specific rule is applied to transform a phrase into a code. To solve this, we need to carefully analyze the given examples to deduce the underlying coding pattern.
Analyzing the Coding Pattern
Let's examine the first example provided:
- Original Phrase: best of luck
- Coded Form: KCLFTSB
Let's break down the words in the original phrase and compare them with the code. Upon careful observation, we can deduce a two-step pattern:
- Consonant Extraction and Reversal: For each word in the original phrase, identify all the consonants. Then, write these consonants in the reverse order of their appearance within that specific word.
- Concatenation: Combine the reversed consonant strings from each word. The order of concatenation is crucial: start with the result from the last word of the phrase, then the second-to-last word, and so on, until the first word.
Let's apply this pattern to the first example to verify:
| Word | Consonants | Consonants in Reverse Order |
|---|---|---|
| best | B, S, T | T, S, B (TSB) |
| of | F | F (F) |
| luck | L, C, K | K, C, L (KCL) |
Now, concatenate these results in the order: 'luck' → 'of' → 'best'.
KCL (from 'luck') + F (from 'of') + TSB (from 'best') = KCLFTSB
This perfectly matches the given coded form for 'best of luck'.
Verifying with the Second Example
Let's confirm this rule using the second example:
- Original Phrase: good wishes
- Coded Form: SHSWDG
Applying the same two-step pattern:
| Word | Consonants | Consonants in Reverse Order |
|---|---|---|
| good | G, D | D, G (DG) |
| wishes | W, S, H, S | S, H, S, W (SHSW) |
Concatenate these results in the order: 'wishes' → 'good'.
SHSW (from 'wishes') + DG (from 'good') = SHSWDG
This also perfectly matches the given coded form for 'good wishes'. The rule is consistent and confirmed.
Applying the Rule to 'ace the exam'
Now that the coding rule is established, we will apply it to the phrase 'ace the exam' to find its coded form.
Original Phrase: ace the exam
| Word | Consonants | Consonants in Reverse Order |
|---|---|---|
| ace | C | C (C) |
| the | T, H | H, T (HT) |
| exam | X, M | M, X (MX) |
Finally, concatenate the results from the last word ('exam') to the first word ('ace'):
MX (from 'exam') + HT (from 'the') + C (from 'ace') = MXHTC
Conclusion
The coded form for 'ace the exam' is MXHTC.
Important Questions from Critical Reasoning
As a responsible person, which of the following is not advisable?
- A, B, and C have a few chocolates among themselves. A gives to each of the other two half the number of chocolates they already have. Similarly B and C (in that order) give each of the other two half the number of chocolates each of them already has. Now, if each of them has the same number of chocolates, what could be the minimum number of chocolates they have among themselves?
