A person Vikram can clearly see objects situated between 25 cm and...

The near point of an eye is determined by the maximum accommodation power of the eye lens, which is achieved when the ciliary muscles are fully contracted.

Stronger ciliary muscles can contract more, increasing the maximum curvature and power of the eye lens. This allows the eye to focus on closer objects, decreasing the near point distance. Thus, Rohan's near point will be less than $25 \text{ cm}$.

The far point is determined by the minimum power of the eye lens, which occurs when the ciliary muscles are fully relaxed.

Since all other parameters of the eye are identical, the fully relaxed state of the lens is the same for both individuals. The strength of the muscles does not affect the relaxed state of the lens.

Therefore, the far point remains unchanged at $200 \text{ cm}$.

The range of clear vision for Rohan could be $18 \text{ cm}$ to $200 \text{ cm}$.
