I want to calculate rank and percent rank

In report i have slicer Date, Category 

Ranking is based on 1daysales by the selection of date and category 
percent rank forumula= ranking*100/counta(1daysales)

Note :- if its blank dont assign rank and percent rank

@Anshenterprices , Create two measures like

Rank = rankx(filter(allselected(Table[DAte], Table[Category]), [Category] =max([category]) ), calculate(sum(table[1DaySales])))

count Day = calculate(count(Table[Date]), filter(allselected(Table), Table[Date] = max(Table[Date]) && Table[category] = max(Table[category]) ))

and then %

% = divide([Rank], [count day])

@amitchandak  thank you
forgot to mentioned in the post, In a table there is also one column i.e. online/offline category , 
I have used online/offline category as a Slicer in the report,but dont want seperate raking and percent rank  once i select online or offline category. it should be same in both ways
