Question
If ‘relftaga’ means carefree, ‘otaga’ means careful and ‘fertaga’ means careless, which of the following could mean ‘aftercare’?
Correct answer
(C) tagazen
Solution
To solve this, we analyze the structure of the given words:
1.Analyze the examples:
- relftaga = carefree
- otaga = careful
- fertaga = careless
- All English words contain the root "care".
- All code words contain the suffix "taga".
- Therefore, taga corresponds to care.
- In English: Root + Suffix (e.g., Care + free).
- In Code: Prefix + Root (e.g., relf + taga).
- This indicates a reversal of the components: English Code .
- carefree (Care + free) relftaga (relf + taga). So, relf = free.
- careful (Care + ful) otaga (o + taga). So, o = ful.
- careless (Care + less) fertaga (fer + taga). So, fer = less.
- Structure: After + Care.
- Based on the reversal rule, the code should be: .
- Since , the code must start with taga.
- (A) zentaga: Ends in taga. Incorrect order.
- (B) tagafer: Starts with taga, but ends with "fer". We know from "fertaga" that "fer" means "less". So "tagafer" would mean "lesscare" (or similar). Incorrect.
- (C) tagazen: Starts with taga, followed by "zen". Since "zen" is a new element corresponding to "after", this fits the structure perfectly.
- (D) relffer: Does not contain taga. Incorrect.
