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

The correct option is Priti.

To find the slowest runner, we can break down the statements and represent the relationship between their running speeds step-by-step:

1. "Usha runs faster than Kamala" means Usha's speed is greater than Kamala's speed:
Usha > Kamala

2. "Swati runs slower than Kamala" means Kamala's speed is greater than Swati's speed:
Kamala > Swati

3. "Priti runs slower than Swati" means Swati's speed is greater than Priti's speed:
Swati > Priti

By combining these individual relationships, we can write a single continuous chain from the fastest runner to the slowest runner:
Usha > Kamala > Swati > Priti

From this sequence, it is clear that Usha is the fastest runner, while Priti runs the slowest. Therefore, Priti is the slowest runner.
