Assignments Of Class 7: Advanced Formulas and Functions
Advanced Formulas and Functions - Assignments with Steps and Solutions
Below are a few assignments based on the concepts of Logical Functions, Lookup Functions, and Text Functions covered in the lecture notes. Each assignment includes step-by-step instructions and solutions to reinforce learning.
Assignment Example:
Assignment 1: Using Logical Functions
Task: Determine if an employee gets a bonus based on performance in two categories. The employee must score 80 or above in both categories to receive a bonus.
Solution: Use the AND function combined with IF:
=IF(AND(A1>=80, B1>=80), "Bonus", "No Bonus")
This formula checks if both scores are 80 or higher and returns "Bonus" if true, or "No Bonus" if false.
Assignment 2: Lookup Function (VLOOKUP)
Task: Use VLOOKUP to find the price of a product based on its name from a list of products and prices.
Solution:
=VLOOKUP("Product A", A2:B10, 2, FALSE)
This formula searches for "Product A" in the first column of the range A2:B10 and returns the corresponding price from the second column.
Assignment 3: Text Function (CONCATENATE)
Task: Combine the first name in cell A1 and the last name in cell B1, separating them with a space.
Solution:
=CONCATENATE(A1, " ", B1)
This formula combines the values of cells A1 and B1 with a space in between.
Conclusion:
In this lesson, we covered three advanced categories of functions in Excel: Logical Functions (IF, AND, OR), Lookup Functions (VLOOKUP, HLOOKUP, INDEX, MATCH), and Text Functions (CONCATENATE, LEFT, RIGHT, MID). These functions allow you to perform complex calculations, search for data, and manipulate text in powerful ways.
Advanced Formulas and Functions - Assignments with Steps and Solutions
Below are a few assignments based on the concepts of Logical Functions, Lookup Functions, and Text Functions covered in the lecture notes. Each assignment includes step-by-step instructions and solutions to reinforce learning.
Assignment 1: Using Logical Functions (IF, AND, OR)
Problem Statement:
You have a list of student scores in two subjects, Math and English. You need to:
- Determine if the student passed or failed based on their Math score (>= 50).
- Check if the student passed both Math and English (>= 50 in both).
- Check if the student passed either Math or English.
Steps and Solution:
- Step 1: Using the IF Function
- Objective: Determine if the student passed or failed in Math.
- Formula:
=IF(A2>=50, "Pass", "Fail")
- Explanation: This formula checks if the Math score (cell A2) is greater than or equal to 50. If true, it returns "Pass"; otherwise, "Fail."
- Step 2: Using the AND Function
- Objective: Determine if the student passed both Math and English.
- Formula:
=IF(AND(A2>=50, B2>=50), "Passed Both", "Failed One or Both")
- Explanation: The AND function checks if both the Math score (A2) and English score (B2) are greater than or equal to 50. The IF function then returns "Passed Both" if both are true, or "Failed One or Both" if false.
- Step 3: Using the OR Function
- Objective: Determine if the student passed either Math or English.
- Formula:
=IF(OR(A2>=50, B2>=50), "Passed One or Both", "Failed Both")
- Explanation: The OR function checks if either the Math score (A2) or English score (B2) is greater than or equal to 50. The IF function returns "Passed One or Both" if either condition is true, or "Failed Both" if both are false.
Solution Output:
Student | Math Score | English Score | Pass/Fail (Math) | Passed Both Subjects | Passed One or Both |
John | 65 | 70 | Pass | Passed Both | Passed One or Both |
Mary | 40 | 80 | Fail | Failed One or Both | Passed One or Both |
Alex | 50 | 45 | Pass | Failed One or Both | Passed One or Both |
Lisa | 30 | 35 | Fail | Failed One or Both | Failed Both |
Assignment 2: Using Lookup Functions (VLOOKUP, HLOOKUP, INDEX, MATCH)
Problem Statement:
You have a list of products and their prices in a table. Your task is to:
- Use VLOOKUP to find the price of a product based on its name.

and returns the corresponding value from the second column (price).
- Solution: The result will be $15.
- Step 2: Using INDEX and MATCH
- Objective: Find the price of "Product C" using INDEX and MATCH.
- Formula:
=INDEX(B2:B4, MATCH("Product C", A2:A4, 0))
- Explanation: The MATCH function finds the position of "Product C" in the range A2
(returns 3). The INDEX function then uses this position to return the corresponding price from column B (3rd row).
- Solution: The result will be $12.
Solution Output:
Product | Price | Looked-up Price (VLOOKUP) | Looked-up Price (INDEX-MATCH) |
Product A | $10 | - | - |
Product B | $15 | $15 | - |
Product C | $12 | - | $12 |
