XAT Selection With Condition Questions

XAT Selection with Condition Questions is a moderately important topic of the XAT QA and DI section, where candidates must solve problems involving logical selection based on given constraints or conditions. These questions typically present a scenario with multiple choices or alternatives and a set of rules or criteria that govern the selection process. Candidates are required to analyze the conditions, evaluate the options, and determine the best or most suitable choice that satisfies all the given requirements.

Understanding the XAT syllabus and knowing all important topics at one place and preparing them is vital as it helps candidates focus their preparation effectively. We have compiled all the previously repeated questions with detailed solutions. You could also download them as PDF. To get a good quality number of questions to practice, getting enrolled in a XAT crash course will help you to streamline your preparation and enhance further.

XAT Selection With Condition Questions

Question 1

Students from four sections of a class accompanied by respective class teachers planned to go for a field trip. There were nineteen people in all. However, on the scheduled day one of the four teachers and a few students could not join the rest. Given below are some statements about the group of people who ultimately left for the trip.
I: Section A had the largest contingent.
Il: Section B had fewer students than Section A.
Ill: Section C's contingent was smaller than Section B.
IV: Section D had the smallest contingent.
V: The product of the number of student from each section is a multiple of 10.
VI: The number of students from Section C is more than 2.
VIl. The product of the number of students from each section is a multiple of 24.
VIll. The largest contingent has more than 4 students.
IX: Each section contributed different number of students
The statements that taken together can give us the exact number of students from each section:

I, II, III, IV, VI

I, VI, Vlll, IX

I, II, III, IV, V, VI

I, II, III, IV, VI, VII

I, IV, VI, VII, IX

Solution

Option A: we get that A>B>C>D and C>2

Option B: we get A is the largest, C>2, A>4 and every section has a different number of students.

Option C: we get that A>B>C>D, C>2 and A*B*C*D = 10n

Option D: we get A>B>C>D, C>2 and A*B*C*D = 24n

Option E: we get A is the largest, D is the smallest, C>2, A*B*C*D = 24n, and each section has a different number of students.

Statement 9 tells us that each section contributes a different number of students and thus this statement is a must in figuring out each section’s strength.

Thus, options A, C and D are eliminated. From option B we cannot figure out any value since we don’t have any relation between their values. Hence, option B is eliminated.

Option E tells us about the largest and smallest section, also provides a relation between all their values which can be used to find out possible solutions and also tells us that each section contributes a different number of students which can be used to eliminate the undesirable results.

Thus, option E is the answer.

Questions are based on a set of conditions. In answering some of the questions, it may be useful to draw a rough diagram. Choose the response that most accurately and completely answers each question.

In a local pet store, seven puppies wait to be introduced to their new owners. The puppies, named Ashlen, Blakely, Custard, Daffy, Earl, Fala and Gabino, are all kept in two available pens. Pen 1 holds three puppies, and pen 2 holds four puppies.

If Gabino is kept in pen 1, then Daffy is not kept in pen 2.
If Daffy is not kept in pen 2, then Gabino is kept in pen 1.
If Ashlen is kept in pen 2, then Blakely is not kept in pen 2.
If Blakely is kept in pen 1, then Ashlen is not kept in pen 1.

Question 1

Which of the following groups of puppies could be in pen 2?

Gabino, Daffy, Custard, Earl.

Blakely, Gabino, Ashlen, Daffy.

Ashlen, Gabino, Earl, Custard.

Blakely, Custard, Earl, Fala.
