Six neighbours, Gauri, Harsh, Ishaan, Jaya, Kunal and Leela, each live on a different floor of a six-floor block, floors numbered one (lowest) to six (top). Ishaan lives on the top floor and Jaya on the lowest. Exactly one floor lies between Gauri's and Harsh's floors, Harsh being higher. Leela lives immediately above Gauri. Kunal lives on an even-numbered floor. How many people live between Kunal and Harsh?

Question

Accepted Answer

Two. Gauri/Harsh can be on floors 2/4 or 3/5. If 2/4, Leela is on 3 and Kunal on 5, which is odd, so this fails. Hence Gauri 3, Harsh 5, Leela 4, Kunal 2 (with Jaya 1 and Ishaan 6). Kunal is on floor 2 and Harsh on floor 5; Gauri and Leela live between them: two people.
