This question was previously asked in
RRB NTPC 2019 CBT 1 Question Paper (8-Mar-2021) (Shift 2)
The correct answer is
M1, W5, W4, M4, W3

The objective is to identify the correct team selection of 5 members from 5 men and 6 women, adhering to specific constraints and a condition regarding the number of women.

Team Selection Conditions & Constraints

  • Team Size: Exactly 5 members.
  • Minimum Women: At least 3 women must be in the team.
  • M2/M5 Pairing: M2 and M5 must be selected together or not at all.
  • M1/M3 Exclusion: M1 and M3 cannot be selected together.
  • M5 Exclusion Rule: If M5 is selected, W4 and M4 cannot be selected.
  • W6 Exclusion Rule: If W6 is selected, M2, W1, and W2 cannot be selected.
  • W5 Exclusion Rule: If W5 is selected, W6, W2, and M2 cannot be selected.

Analysis of Team Selection Options

Option 1: {M2, W2, W4, M5, W6}

  • Women Count: 3 (W2, W4, W6) - Meets the minimum requirement.
  • M2/M5 Pairing: M2 and M5 are present. - OK.
  • Constraint Violation: W6 is selected, but M2 is also selected. This violates the rule "W6 cannot be selected with M2".
  • Constraint Violation: M5 is selected, but W4 is also selected. This violates the rule "M5 cannot be selected with W4".

This option is incorrect due to multiple constraint violations.

Option 2: {M2, W3, M5, M3, W2}

  • Women Count: 2 (W3, W2) - Does NOT meet the minimum requirement of 3 women.

This option is incorrect as it fails the primary condition.

Option 3: {M1, W5, W4, M4, W3}

  • Women Count: 3 (W5, W4, W3) - Meets the minimum requirement.
  • M2/M5 Pairing: Neither M2 nor M5 is selected. - OK.
  • M1/M3 Exclusion: M1 is selected, M3 is not selected. - OK.
  • M5 Exclusion Rule: M5 is not selected. - OK.
  • W6 Exclusion Rule: W6 is not selected. - OK.
  • W5 Exclusion Rule: W5 is selected. The excluded members (W6, W2, M2) are not selected. - OK.

This option satisfies all conditions and constraints.

Option 4: {M1, W2, W4, W6, M3}

  • Women Count: 3 (W2, W4, W6) - Meets the minimum requirement.
  • M1/M3 Exclusion: M1 and M3 are both selected. - VIOLATES the rule "M1 cannot be selected with M3".

This option is incorrect due to violating the M1/M3 exclusion rule.

Conclusion

Based on the analysis, only Option 3 meets all the specified requirements for team selection.
