Data Sufficiency — shortest distance between two towns Towns: Devipur, Durgapur, with Rampur as a reference point. Statements: I. Durgapur is 20 km from Rampur. II. Devipur is 15 km from Rampur. Choose the correct sufficiency option.

Difficulty: Easy

I alone is sufficient while II alone is not sufficient
II alone is sufficient while I alone is not sufficient
Either I or II is sufficient
Neither I nor II is sufficient

Correct Answer: Neither I nor II is sufficient

Explanation:

Geometry insight
Knowing distances from Rampur only gives radii 20 km and 15 km around Rampur. The Devipur–Durgapur distance could be anywhere from |20−15| = 5 km (same ray) up to 35 km (opposite directions).

Conclusion
Neither I nor II is sufficient to give a unique shortest distance.
