In my excel sheet, i am having 5 data cells in a single row.Among the first 4 cells if any three data are above 70 ,then the 5th cell value should be set to 15.If any three cells value are above 60 but less than 70, then 5th cell value should be set to 13. If any two cells value are above 60 and other two are below 50 ,then 5th cell value should be set to 12.If any two cells value are above 50 but below 60 and other two are below 50 ,then 5th cell value should be set to 11. If only one cell among the four cells is having the value 50 or more than 50, then 5th cell value should be set to 10.If all the four cells are having less than 50,then 5th cell value should be set to 5.Help me to write a formula for the 5th cell.
