To understand inclination of students towards various subjects, three students are asked to give their preference for three subjects: Mathematics, Science and History. Each student either preferred or did not prefer each subject. Two students selected History, one student selected Science, two students selected Mathematics. Student 1 does not select Mathematics and Science. Student 2 selects subjects except Science. Student 3 does not select History. Which of the following statements is true?
Correct answer: C
Explanation
Since only one student took Science and neither Student 1 nor Student 2 could, Science goes to Student 3. History needs two takers but Student 3 cannot, so History goes to Students 1 and 2. Mathematics needs two takers but Student 1 cannot, so Maths goes to Students 2 and 3. That leaves Student 1 with History only, Student 2 with Maths and History, and Student 3 with Science and Maths, which makes option (c) true.
