R `to` to the immediate right of T.
`cdot " "S to`
`cdot " "P to" facing"`
`cdot " "T to" east"`
`cdot" "R to `
Fig. : Row arrangement But there is no information regarding Q. So, statement I alone is not sufficient.
From statement II :
Between T and Q `to` R .
`cdot " "T to" facing"`
`cdot" "R to " east"`
`cdot" "Q rarr` Fig. : Row arrangement But there is no information regarding P and S. So, statement II alone is not sufficient.
From I & II, we get
Extreme left end . `cdot " "S to`
`cdot " "P to" facing"`
`cdot " "T to" east"`
`cdot" "R to `
Extreme right end. `cdot" "Q to`
Fig. : Final Row arrangement
So, At the extreme right end `to` Q.
Therefore, the data in both statement I and II together are necessary to answer the given question.
