To solve the problem, let's analyze the constraints and derive a sequence in which the girls can be served:
- Constraints analysis:
- Mohita and Jyoti cannot be served one after the other.
- Neena cannot be served third in the sequence.
- Radha and Neena must be served one after the other.
- Determine the feasible sequence:
- Since Radha and Neena are to be served together, they can appear in two possible places in the sequence: first-second or third-fourth.
- If Radha and Neena are in the first and second positions, Jyoti and Mohita are left for the third and fourth positions. However, Mohita and Jyoti cannot be consecutive, which makes this situation impossible.
- Thus, Radha and Neena must occupy the third and fourth positions.
- Among the positions together, Neena cannot be third according to the constraint, so Radha must be third, and Neena must be fourth.
- Satisfying remaining constraints:
- With Radha in the third position and Neena in the fourth, Mohita and Jyoti must take the first and second positions.
- As Mohita and Jyoti cannot be consecutive, this order ensures compliance with the rule.
Therefore, the sequence that satisfies all constraints is: Either Jyoti - Mohita - Radha - Neena or Mohita - Jyoti - Radha - Neena. Thus, the compulsorily true statement is that Radha will be served third.
