Assume a two column database with names in column A and numbers in column B. Names in column A may be repeated. If a user types a certain name in a cell, a formula should sum the highest three values from column B for that name.

Depending upon the version of MS Excel which you are using, there could be two ways to solve this problem

**Solution for MS Excel 2010 and higher versions**

If you are using the PowerPivot add-in, then a simple DAX formula can solve this problem.

**Solution for all versions of MS Excel**

While this solution works for all versions of MS Excel, it uses an array formula (Ctrl+Shift+Enter). Array formulas, if used extensively in the workbook, adversely effect the system's performance.

In range A2:A6, the numbers are 7.5, 2, -12, 11.2 and 8. In cell B8, a user enters 8. One may want to answer the following questions:

1. Return the closest number which is less than or equal to the number in cell B8

2. Return the closest number which is greater than or equal to the number in cell B8

3. Return the closest match
