Given that: French is easier than Dutch; Chinese is harder than Japanese; Dutch is easier than Japanese, and Spanish is easier than French.
Based on the above information, which girl is learning the most difficult pair of languages?
Language Difficulty Ranking
Establish the relative difficulty of the languages from the given statements:
- Spanish is easier than French: Spanish < French
- French is easier than Dutch: French < Dutch
- Dutch is easier than Japanese: Dutch < Japanese
- Chinese is harder than Japanese: Japanese < Chinese
Combining these inequalities gives the complete difficulty order from easiest to hardest:
Spanish < French < Dutch < Japanese < Chinese
Analyzing Language Pairs Difficulty
Evaluate the difficulty of the language pair each girl is learning:
- P learns French and Dutch. These languages fall in the lower-middle range of difficulty.
- Q learns Chinese and Japanese. These are the two hardest languages according to the ranking.
- R learns Spanish and French. These are the two easiest languages.
- S learns Dutch and Japanese. This pair includes a middle-difficulty language and a hard language.
Identifying Most Difficult Pair
Compare the pairs based on the established difficulty ranking:
- R's pair (Spanish, French) is the easiest.
- P's pair (French, Dutch) is of intermediate difficulty.
- S's pair (Dutch, Japanese) is harder than P's pair.
- Q's pair (Chinese, Japanese) comprises the two highest-ranked difficult languages.
Therefore, girl Q is learning the most difficult pair of languages.
Important Questions from Analytical Aptitude
