Sudhanshu is as much older than Kokila as he is younger than Praveen. Nitin is as old as Kokila. Which of the following statement is wrong ?
Answer: D. Praveen is not the oldest.
In terms of age we have : Kokila < Sudhanshu, Sudhanshu < Praveen, Nitin = Kokila. So, the sequence becomes : Nitin = Kokila < Sudhanshu < Praveen. Clearly, Praveen is the oldest. Hence, (d) is the incorrect statement.
