## Grouping and Team Formation

#### Grouping and Team Formation

Direction: A scientist is trying to find a cure for the common cold using four ingredients. He can choose from the stable chemicals A, B and C and the unstable chemicals W, X, Y and Z. In order for the formula not to explode, there must be two stable chemicals cannot be mixed because of their reaction together. Chemicals B cannot be mixed with chemicals W. Chemicals C cannot be mixed with chemicals Y. Chemicals Y cannot be mixed with chemicals Z.

1. Which of the following can never be true?
I. If chemical C is used, chemical Z is added.
II. If chemical B is not used, chemical Y is added.
III. If chemical C is used, chemical W is

1. As per the given above question , we can say that
If B is not used and Y is added then W is selected and C is rejected respectively.

##### Correct Option: D

As per the given above question , we can say that
If B is not used and Y is added then W is selected and C is rejected respectively. Again problem appear in fulfill the no. stable of ingredients.

1. Which of the following combinations of chemicals is impossible?
I. Using chemical Y and W together.
II. Using chemical B and C together.
III. Using chemical W, X and Z together.

1. According to the given Option iii) said 3 unstable chemical so, there must be 1 stable.

##### Correct Option: A

According to the given Option iii) said 3 unstable chemical so, there must be 1 stable, which is also impossible.

1. The scientist rejected chemical B because of its possible side effects but decided to use chemical Z. Which is a possible combination of the four ingredients in the formula?

1. Given in the question ,
If B rejected so W can be mixed and Z is present, Y can't mixed.

##### Correct Option: B

Given in the question ,
If B rejected so W can be mixed and Z is present, Y can't mixed.
Again we 2 stable ingredients. So, A & C will be there.

1. If the scientist calculated that Y is the most important chemical and must be used in the formula, which other ingredients must be a part of the cure?

1. On the basis of above given information , we can say that
Stable chemicals A, B and C and the unstable chemicals W, X, Y and Z. Chemicals cannot be mixed with another chemical - B/W, C/Y, Y/Z.

##### Correct Option: D

On the basis of above given information , we can say that
Stable chemicals A, B and C and the unstable chemicals W, X, Y and Z. Chemicals cannot be mixed with another chemical - B/W, C/Y, Y/Z.
If Y is present then Z&C can't be with it.
Among 4 ingredients there must be 2 stable ingredients . So, they are A and B and only unstable is x because due to presence of B.
