Practice - 5 Tasks

1fill in blank

easy

Complete the formula to check if either A1 or B1 is TRUE using the OR function.

Excel

=OR([1])

Drag options to blanks, or click blank then click option'

AA1, B1

BA1 B1

CA1; B1

DA1+B1

💡 Hint

Common Mistakes

Using spaces or plus signs instead of commas between arguments.

Using semicolons which are not valid separators in Excel formulas.

The OR function takes arguments separated by commas. So =OR(A1, B1) checks if either A1 or B1 is TRUE.

Complete the formula to check if the value in C2 is greater than 10 or less than 5.

Excel

=OR(C2 [1] 10, C2 [2] 5)

Drag options to blanks, or click blank then click option'

A!=

B<

C=

D>

💡 Hint

Common Mistakes

Using the wrong comparison operator like '=' or '<' for the first condition.

Confusing greater than and less than operators.

The formula should check if C2 is greater than 10 or less than 5. The first comparison is C2 > 10 and the second is C2 < 5.

Fix the error in the formula to correctly check if D3 equals 5 or 10 using OR.

Excel

=OR(D3=[1], D3=10)

Drag options to blanks, or click blank then click option'

A5

B"5"

C5.0

Dfive

💡 Hint

Common Mistakes

Putting numbers inside quotes, which makes them text.

Using words like 'five' instead of numbers.

Since D3 contains a number, use the number 5 without quotes. So D3=5 is correct.

4fill in blank

hard

Fill both blanks to create a formula that checks if E1 is less than 0 or greater than 100.

Excel

=OR(E1 [1] 0, E1 [2] 100)

Drag options to blanks, or click blank then click option'

A<

B>

C=

D<=

Attempts:

💡 Hint

Common Mistakes

Using equals or less than or equal operators instead of strict less than or greater than.

The formula checks if E1 is less than 0 or greater than 100, so use < and > respectively.

5fill in blank

hard

Fill all three blanks to create a formula that checks if F2 is equal to 1, 2, or 3 using OR.

Excel

=OR(F2=[1], F2=[2], F2=[3])

Drag options to blanks, or click blank then click option'

A1

B2

C3

D4

Attempts:

💡 Hint

Common Mistakes

Including numbers outside the range 1 to 3.

Using text instead of numbers.

The formula checks if F2 equals 1, 2, or 3, so fill blanks with 1, 2, and 3 respectively.

Practice

1. What does the OR function do in Excel?

easy

A. Returns FALSE if any condition inside it is TRUE

B. Returns TRUE if any condition inside it is TRUE

C. Returns TRUE only if all conditions inside it are TRUE

D. Counts how many conditions are TRUE

Solution

1. Step 1: Understand the OR function purpose

   The OR function checks multiple conditions and returns TRUE if at least one condition is TRUE.

2. Step 2: Compare options with OR behavior

   Only Returns TRUE if any condition inside it is TRUE correctly states that OR returns TRUE if any condition is TRUE.

3. Final Answer:

   Returns TRUE if any condition inside it is TRUE -> Option B

4. Quick Check:

   OR = TRUE if any condition TRUE [OK]

Hint: OR returns TRUE if any condition is TRUE, else FALSE [OK]

Common Mistakes:

• Thinking OR requires all conditions TRUE
• Confusing OR with AND function
• Assuming OR counts TRUE conditions

2. Which of these is the correct syntax for the OR function in Excel?

easy

A. =OR(A1>10, B1<5)

B. =OR(A1>10; B1<5)

C. =OR{A1>10, B1<5}

D. =OR[A1>10, B1<5]

Solution

1. Step 1: Recall Excel function syntax

   Excel functions use parentheses () and commas , to separate arguments.

2. Step 2: Check each option's syntax

   =OR(A1>10, B1<5) uses correct parentheses and commas. Options A, B, and C use incorrect separators or brackets.

3. Final Answer:

   =OR(A1>10, B1<5) -> Option A

4. Quick Check:

   Excel functions use () and commas [OK]

Hint: Use parentheses and commas in Excel functions [OK]

Common Mistakes:

• Using semicolons instead of commas
• Using curly or square brackets
• Missing parentheses

3. Given the formula =OR(A1>5, B1=10) with A1=3 and B1=10, what is the result?

medium

A. TRUE

B. FALSE

C. 3

D. 10

Solution

1. Step 1: Evaluate each condition

   A1>5 is 3>5 which is FALSE. B1=10 is 10=10 which is TRUE.

2. Step 2: Apply OR logic

   OR returns TRUE if any condition is TRUE. Since B1=10 is TRUE, OR returns TRUE.

3. Final Answer:

   TRUE -> Option A

4. Quick Check:

   OR(FALSE, TRUE) = TRUE [OK]

Hint: If any condition is TRUE, OR returns TRUE [OK]

Common Mistakes:

• Assuming both conditions must be TRUE
• Confusing OR with AND
• Returning a cell value instead of TRUE/FALSE

4. The formula =OR(A1>5 B1=10) returns an error. What is the fix?

medium

A. Remove parentheses

B. Replace OR with AND

C. Add a comma between conditions: =OR(A1>5, B1=10)

D. Change > to >= in first condition

Solution

1. Step 1: Identify syntax error

   The formula misses a comma between conditions inside OR, causing a syntax error.

2. Step 2: Correct the syntax

   Insert a comma between conditions: =OR(A1>5, B1=10) to fix the error.

3. Final Answer:

   Add a comma between conditions: =OR(A1>5, B1=10) -> Option C

4. Quick Check:

   OR arguments must be comma-separated [OK]

Hint: Separate OR conditions with commas [OK]

Common Mistakes:

• Forgetting commas between conditions
• Replacing OR with AND without reason
• Removing parentheses causing more errors

5. You want to mark a student as 'Pass' if their score in A1 is above 50 or if they have extra credit in B1 (marked TRUE). Which formula correctly does this?

hard

A. =IF(AND(A1>50, B1=TRUE), "Pass", "Fail")

B. =IF(A1>50 OR B1=TRUE, "Pass", "Fail")

C. =IF(OR(A1>50 B1=TRUE), "Pass", "Fail")

D. =IF(OR(A1>50, B1=TRUE), "Pass", "Fail")

Solution

1. Step 1: Understand the condition

   The student passes if score > 50 OR extra credit is TRUE.

2. Step 2: Check formula correctness

   =IF(OR(A1>50, B1=TRUE), "Pass", "Fail") uses IF with OR and correct syntax. =IF(AND(A1>50, B1=TRUE), "Pass", "Fail") uses AND which requires both true, wrong logic. Options C and D have syntax errors (missing commas or wrong structure).

3. Final Answer:

   =IF(OR(A1>50, B1=TRUE), "Pass", "Fail") -> Option D

4. Quick Check:

   Use IF with OR for either condition TRUE [OK]

Hint: Use IF with OR for either condition TRUE [OK]

Common Mistakes:

• Using AND instead of OR
• Missing commas inside OR
• Incorrect IF syntax
