Direction (2 of 4 questions): Read the information given below carefully and answer the questions that follow:
A, B, C, D, E, F and G are seven students at a school, who are studying in seven different Classes V, VI, VII, VIII, IX, X and XI. Every one of them likes a particular subject viz. English, Hindi, Physics, Chemistry, Mathematics, History and Geography. Students, Classes, and subjects can always be in different order as given.
Given Information:
- B likes History and does not study in Class VII.
- The one who likes English studies in Class IX.
- The one who studies in Class V, likes Chemistry.
- F likes Physics.
- C is studying in Class VI and doesn't like Geography.
- E is studying in Class X and likes Mathematics.
- D likes Chemistry.
- G doesn't like English, and G is not in Class VII or VIII.
- F is not in Class VIII.
G is in which Class?
Show answer & explanation
By constraint satisfaction, D is in V (Chemistry), C is in VI, E is in X (Math). G is not in VII or VIII, and G does not like English (which is in IX). Hence G must be in Class XI.
Step-by-step Derivation:
Step 1: Direct assignments: D = Class V (Chemistry), C = Class VI, E = Class X (Math).
Step 2: English is in Class IX. G does not like English, so G is not in Class IX.
Step 3: G is not in Class VII or VIII.
Step 4: The only remaining eligible class for G is Class XI.
