Kabir is heavier than Leena, and Leena is heavier than Manav. Nargis is heavier than Manav. Om is heavier than Kabir. If Nargis is also heavier than Kabir, who is the third heaviest?

Explanation

1. 01

   Om > Kabir > Leena > Manav from the first clues.

2. 02

   With Nargis > Kabir, Nargis must sit above Kabir: either Nargis > Om > Kabir or Om > Nargis > Kabir.

3. 03

   In both orders two people (Om and Nargis) are above Kabir, so Kabir is the third heaviest.

4. 04

   The order of Om and Nargis at the top stays unknown, but it does not change the third place.
