The pattern followed here is,

Let,

“×” means does not sit with

“+” means sit with

Given:

There are two benches A and B and one chair.

Three persons can sit on each of these benches and one on the chair.

Seven persons, Aman, Bhaskar, Chetan, Dablu, Ekta, Fauzia, and Ganesh

(i) Fauzia does not sit on the same bench as Dablu.

  • Fauzia × Dablu

(ii) Ekta does not sit on the same bench as Dablu.

  •  Ekta × Dablu

(iii) Chetan can sit with Aman but not with Ganesh.

  • (Chetan + Aman) × Ganesh

(iv) Aman can sit with Dablu but not with Bhaskar or Ganesh.

  • (Aman + Dablu) × Bhaskar or Ganesh

(v) Ganesh does not sit on the same bench as Fauzia.

  • Ganesh × Fauzia

From Point (iii) and (iv) we get,

Chetan Ganesh and Aman sit on same bench

Bench A

Bench B

Chair

Chetan + Ganesh + Aman

Fauzia / Ekta / Bhaskar / Ganesh

Fauzia / Ekta / Bhaskar / Ganesh

 

But from Point (v) Ganesh does not sit on the same bench as Fauzia.

So,

Bench A

Bench B

Chair

Chetan + Ganesh 

+ Aman

Fauzia + Ekta  + Bhaskar

Ganesh

 

Hence, “Ganesh” is sitting in the chair.
