Explanation

We have:

• Iyer lives on even numbered floor at a gap of three floors from Anuj, whose last name is neither Singh nor Sharma, Age of Sumit is 31 years and lives just below Iyer.
• Sharma neither lives on adjacent floor of Iyer nor lives on top floor.
• Sharma lives two places above Smith, whose age is neither 31 years nor 54 years, Based on the above given information we have:

Again, we have:

• Oberoi lives just below Vicky, whose last name is neither Iyer nor lives above Anuj,
• Difference between the age of Ojha and Oberoi is 23 years, thus only two such combinations are possible (18, 41) & (31, 54).
• Sum of ages of Khan and Anuj is equal to the age of Oberoi, thus only two such combinations are possible (18, 23, 41) & (18, 36, 54).
• Age of Ojha is neither 18 years nor lives adjacent to Anuj, since age of Oberoi is sum of two person thus, age of Oberoi must be either 41 years or 54 years.
• Since, age of Ojha is not 18 years, thus only possible age of Oberoi is 54 years and that of Ojha must be 31 years.

Based on theabove given information we have:

Case (1) is not valid as Oberoi lives just below Vicky, whose last name is neither Iyernor lives above Anuj.

Again, we have:

• Age of Singh is 23 years, as age of last name of Anuj is not Singh.
• Two persons live between Singh and Oberoi Number of person lives below Khan is one less than number of person livesabove Mike, which means Smith’s last name is Khan.
• Rai lives on adjacent floor of the one whose age is 32 years, that means Anuj’slast name is Rai and Sharma’s age is 32.
• David lives three places away from the one whose age is 32 years, that means David lives at floor marked 2.
• Age of Rai is neither 36 years nor 41 years, which means age of Anuj must be 18 years.
• As, remaining person is Anuj and David, thus age of Anuj must be 36 years and age of David is 41 years.

Based on theabove given information we have thefinal arrangement as follow:

Case (2b) &Case (2c) are not valid as two persons live between Singh and Oberoi.
