Challenge - 5 Problems

📊 Formula Result

intermediate

What is the output of this formula consolidating data?

You have three sheets named Jan, Feb, and Mar. Each sheet has sales data in cells A2:A5. The formula =SUM(Jan!A2:A5, Feb!A2:A5, Mar!A2:A5) is entered in a summary sheet. What does this formula return?

A The sum of all sales values from A2 to A5 across Jan, Feb, and Mar sheets combined

B The sum of sales values only from the Jan sheet A2 to A5

C The sum of sales values from the summary sheet cells A2 to A5

D An error because ranges from multiple sheets cannot be summed this way

💡 Hint

Think about how SUM works with multiple ranges from different sheets.

The formula sums all values in the ranges A2:A5 from each sheet Jan, Feb, and Mar, adding them together into one total.

❓ Function Choice

intermediate

Which function best consolidates data from multiple sheets into one list?

You want to create a combined list of all product names from sheets named Store1, Store2, and Store3. Each sheet has product names in column A. Which function is best to consolidate all product names into one column in a summary sheet?

A Use <code>=VLOOKUP()</code> to find products across sheets

B Use <code>=CONCATENATE()</code> to join product names from each sheet

C Use <code>=SUM()</code> to add product names

D Use <code>=FILTER()</code> combined with <code>INDIRECT()</code> to pull product lists dynamically

💡 Hint

Think about how to pull lists dynamically from multiple sheets.

FILTER combined with INDIRECT can dynamically pull and combine lists from multiple sheets into one consolidated list.

Analyzing consolidated sales data from multiple sheets

You consolidated monthly sales data from sheets Jan, Feb, and Mar into a summary sheet using =SUM(Jan!B2:B10, Feb!B2:B10, Mar!B2:B10). You want to find which month had the highest total sales. How can you do this efficiently?

A Use <code>=MAX(Jan!B2:B10, Feb!B2:B10, Mar!B2:B10)</code> to find the highest single sale value

B Calculate each month's total separately with <code>=SUM(Jan!B2:B10)</code>, <code>=SUM(Feb!B2:B10)</code>, <code>=SUM(Mar!B2:B10)</code> and compare

C Use <code>=SUM(Jan:Mar!B2:B10)</code> to get the highest monthly total

D Use <code>=AVERAGE(Jan!B2:B10, Feb!B2:B10, Mar!B2:B10)</code> to find the highest month

💡 Hint

Think about how to get totals per month before comparing.

You must sum each month's data separately to get totals, then compare those totals to find the highest month.

🎯 Scenario

Scenario: Consolidating dynamic data ranges from multiple sheets

You have sheets named Week1, Week2, and Week3. Each week has a different number of sales entries in column A. You want a formula in a summary sheet that sums all sales from all weeks, even if the number of rows changes weekly. Which approach works best?

A Use <code>=SUM(Week1!A2:A5, Week2!A2:A5, Week3!A2:A5)</code> fixed range

B Use <code>=SUM(Week1!A2:A100, Week2!A2:A100, Week3!A2:A100)</code> assuming max 100 rows

C Use <code>=SUM(INDIRECT("Week1!A2:A"&COUNTA(Week1!A:A)), INDIRECT("Week2!A2:A"&COUNTA(Week2!A:A)), INDIRECT("Week3!A2:A"&COUNTA(Week3!A:A)))</code>

D Use <code>=SUM(Week1!A:A, Week2!A:A, Week3!A:A)</code> to sum entire columns

💡 Hint

Think about how to dynamically adjust ranges based on data length.

Using INDIRECT with COUNTA dynamically adjusts the range to sum only the filled rows in each sheet.

📊 Formula Result

expert

What error does this formula produce when consolidating data?

You try to consolidate data with the formula =SUM(Jan:Mar!A2:A5) in Excel. What happens when you enter this formula?

A It returns the sum of A2:A5 from all sheets between Jan and Mar inclusive

B It returns a #REF! error because 3D references cannot be used with SUM

C It returns a #NAME? error because the sheet names are invalid

D It returns a #VALUE! error because ranges across sheets must be summed individually

💡 Hint

Think about how Excel handles 3D references in SUM.

Excel supports 3D references like Jan:Mar!A2:A5 in SUM to sum the same range across multiple sheets between Jan and Mar.
