Hi @PrasanthSara22 

Here is my solution with Power Query. Hope it helps. 

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtY31Dc2UNJRcgRip6LUxGwgbWigFKuDW9oIv7QxprQTfsORpU0JycYCAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Name = _t, Activity = _t, Time = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Name", type text}, {"Activity", type text}, {"Time", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Date", "Name"}, {{"All Rows", each Table.AddIndexColumn(_, "Index", 1, 1), type table}, {"Total", each List.Sum([Time]), type nullable number}}),
    #"Removed Other Columns" = Table.SelectColumns(#"Grouped Rows",{"All Rows", "Total"}),
    #"Expanded All Rows" = Table.ExpandTableColumn(#"Removed Other Columns", "All Rows", {"Date", "Name", "Activity", "Time", "Index"}, {"Date", "Name", "Activity", "Time", "Index"}),
    #"Replaced Value" = Table.ReplaceValue(#"Expanded All Rows", each if [Index] <> 1 then [Total] else false, each 0, Replacer.ReplaceValue, {"Total"})
in
    #"Replaced Value"

Does it have to be DAX?  Would be much simpler in Power Query.
