Selection Problem

In this type of question, you have to select a team of say ‘a’ members from ‘n’ that are available for the selection. Here n > r and the committee selects a certain number of members. There are certainly some constraints which will influence this selection. The individual has to keep in mind the conditions and make the required selection. This will be better understood by seeing an example.

Examples For You

Q. A team of five members is to be selected. There are five boys namely P, Q, R, S, and T are given and four girls namely W, X, Y, and Z for the selection. There are certain conditions for the selection. They are as follow.

P and Z are always together.

X and Y are never together.

Q and Y are never in the same group.

R and T always stay together.

X and S are never together.

Let us see more Questions

Q. If P and R are the two members of the group than the other members that cannot be in the same group are _______.

A. Q T Z

B. S T Z

C. T Z W

D. W X T

We know that when P is selected that Z should also be selected and when R is selected than T should also be selected. Thus Z and T will be the other two members of the group. The only option that does not have Z and T is the option (4). So the correct answer is (4).

Q. If the two members of the group are girls and S is one of them, then what will be the other members of the group?

A. W X Q R

B. W X R T

C. W Z P Q

D. W Z R T

If S is selected then we cannot select X. So the option (A) and (B) are not possible. P and Z should be in the same group. So option (D) negated. This leaves with the only option available to us i.e. option (C). So, the correct answer is (C).
