1. Three friends, Vinitha, Mira and Neethu, had lunch at a hotel.

2. When the bill was received, Vinitha paid 2/3 as much as Mira paid and Mira paid 1/2 as much as Neethu paid.

Vinitha = Mira       ---(i)

Mira =  Neethu

2 Mira = Neethu       ---(ii)

As, the total bill was divided among them

So, Vinitha + Mira + Neethu = 1       ---(iii)

Substituting the value of (i) and (ii) in (iii), we get:

Mira + Mira + 2 Mira = 1

Mira = 3/11

After reading statement and conclusion we say that -

ii) Some people who are good at dance are pianists. → True ( As all pianists are good dancer means some of the good dancers are pianists) 

Hence, "Only conclusion ii) follows" is the correct answer.
