Question

If the team consists of two doctors, one engineer and four teachers, all the following teams are possible except

• A. A B G M N O P
• B. A B H M O P Q
• C. A B H M R P Q
• D. A B K N R P Q

Answer 1

Answer: (D)

A B K N R P Q

The doctors are A, B, C, D and E; engineers are G, H, K and L; teachers are M, N, O, P, Q and R. Four teachers are needed. There are three male teachers. So, female teachers are also to be selected. So, male doctors i.e. C, D and E cannot be selected. Thus, the two doctors selected will be A and B.

Both the doctors selected are females. So, male engineer K or L cannot be selected and either G or H is to be chosen.

Clearly, the impossible team is A B K N R P Q, because K is not to be selected.
