sayali_deshmukh ,

Create two calculate columns using dax as below:

Rank = RANKX(FILTER('Table', 'Table'[Type] = EARLIER('Table'[Type]) && 'Table'[Category] = EARLIER('Table'[Category])), 'Table'[Index], , ASC, Dense)

Column = 
VAR Current_Rank = 'Table'[Rank]
VAR Current_CumulativeDaily = 'Table'[CumulativeDaily]
RETURN
    IF (
        Current_Rank = 1,
        Current_CumulativeDaily,
        Current_CumulativeDaily
            - CALCULATE (
                MAX ( 'Table'[CumulativeDaily] ),
                FILTER (
                    'Table',
                    'Table'[Category] = EARLIER ( 'Table'[Category] )
                        && 'Table'[Type] = EARLIER ( 'Table'[Type] )
                        && 'Table'[Rank] = Current_Rank - 1
                )
            )
    )
