36 : - is correct hence option 4
(Ram + Rahim) / 2 = 18
Ram + Rahim = 36
Similarly
Rahim +Ramesh = 50
Ram + Ramesh = 58
(Ram + Rahim + Ramesh) / 2 = 144
Ram + Rahim + Ramesh = 72
Eldest is Ramesh = (Ram + Rahim + Ramesh ) - (Ram + Rahim) = 72 - 36 = 36
Hence 36 is the right answer
(Ram + Rahim) / 2 = 18
Ram + Rahim = 36
Similarly
Rahim +Ramesh = 50
Ram + Ramesh = 58
(Ram + Rahim + Ramesh) / 2 = 144
Ram + Rahim + Ramesh = 72
Eldest is Ramesh = (Ram + Rahim + Ramesh ) - (Ram + Rahim) = 72 - 36 = 36
Hence 36 is the right answer
