Answer 1

Use keyfind function from lists module. For example:

30> List = [{"A1",["ankit","sush", "Hover", "x4", "a3","nilesh","mike","erlang"]}].
[{"A1",
  ["ankit","sush","Hover","x4","a3","nilesh","mike",
   "erlang"]}]
31> lists:keyfind("A1", 1, List).
{"A1",
 ["ankit","sush","Hover","x4","a3","nilesh","mike","erlang"]}
