Usha runs faster than Kamla, Priti runs slower than Swati, Swati runs slower than Kamala. Who is the slowest runner?

Correct Option (B)

The problem requires determining the slowest runner by establishing a comparative order of speeds based on the given statements:

• Statement 1: Usha runs faster than Kamla (Usha > Kamla).
• Statement 2: Priti runs slower than Swati (Swati > Priti).
• Statement 3: Swati runs slower than Kamla (Kamla > Swati).

By combining these relationships, a complete order of speed can be derived:

1. From Statement 1, Usha is faster than Kamla.
2. From Statement 3, Kamla is faster than Swati.
3. Combining these, the sequence becomes Usha > Kamla > Swati.
4. From Statement 2, Swati is faster than Priti.
5. Integrating this into the sequence yields the complete order: Usha > Kamla > Swati > Priti.

This final sequence indicates that Priti is the slowest runner.

Incorrect Options:

Based on the derived order Usha > Kamla > Swati > Priti:

• Kamala (A) is faster than both Swati and Priti.
• Swati (C) is faster than Priti.
• Usha (D) is the fastest runner among all.

Therefore, options A, C, and D are incorrect as they do not represent the slowest runner.
