Calculate total sales using SUM function

You have a list of sales amounts in cells B2:B10. Which formula correctly calculates the total sales?

A =SUM(B2:B10)

B =SUM(B2+B10)

C =SUM(B2:B10, B11)

D =SUM(B2;B10)

💡 Hint

Use the function that adds all numbers in a range.

The SUM function adds all numbers in the specified range. Option A correctly sums all values from B2 to B10. Option A sums only two cells, not the range. Option A includes an extra cell B11 which may be empty or unrelated. Option A uses a semicolon which is invalid in Excel formulas.

❓ Function Choice

intermediate

Choose the correct aggregation function for average

You want to find the average value of numbers in cells C2:C15. Which function should you use?

A SUM(C2:C15)

B AVERAGE(C2:C15)

C MAX(C2:C15)

D COUNT(C2:C15)

💡 Hint

Think about which function calculates the mean value.

The AVERAGE function calculates the mean of the numbers in the range. SUM adds them, COUNT counts how many numbers there are, and MAX finds the largest number.

🎯 Scenario

Summing values with conditions using SUMIF

You have sales data in column D and product categories in column C. You want to sum sales only for the category "Electronics". Which formula will do this?

A =SUMIF("Electronics", C2:C20, D2:D20)

B =SUMIF(D2:D20, "Electronics", C2:C20)

C =SUMIF(C2:C20, D2:D20, "Electronics")

D =SUMIF(C2:C20, "Electronics", D2:D20)

💡 Hint

Remember the order: range to check, condition, then sum range.

The SUMIF function syntax is SUMIF(range, criteria, sum_range). Option D correctly sums sales in D2:D20 where the category in C2:C20 equals "Electronics". Other options mix the order or arguments incorrectly.

Finding the maximum value ignoring blanks

Column E contains sales numbers but some cells are blank. Which formula correctly finds the maximum sales value ignoring blanks?

A =MAX(IF(ISNUMBER(E2:E30), E2:E30))

B =MAX(IF(E2:E30<>"", E2:E30))

C =MAX(E2:E30)

D =MAX(E2:E30, "")

💡 Hint

Use a formula that checks if cells contain numbers before finding max.

Option A uses an array formula with IF(ISNUMBER(...)) to ignore blanks or text. Option A includes blanks but they don't affect max. Option A is an array formula but comparing to empty string may cause errors. Option A is invalid syntax.

Understanding aggregation behavior with pivot tables

In a pivot table, you add a value field showing sales amounts. By default, what aggregation does Excel apply to this value field?

A Count of sales amounts

B Average of sales amounts

C Sum of sales amounts

D Maximum of sales amounts

💡 Hint

Think about what Excel usually does with numbers in pivot tables.

By default, Excel sums numeric values in pivot table value fields. If the field contains text, it counts instead. So for sales amounts (numbers), the default aggregation is sum.
