4. 4.In MS Excel, which function would you use to find the largest value in a range of cells A1 to A10?

   • (A)=SUM(A1:A10)
   • (B)=AVERAGE(A1:A10)
   • (C)=MAX(A1:A10)
   • (D)=COUNT(A1:A10)
   Show the answer and solution

   Answer: (C) =MAX(A1:A10)

   Solution: MS Excel provides various built-in functions for data analysis. Let us examine each option: Option A: SUM function adds all values in the range and returns the total. Option B: AVERAGE function calculates the arithmetic mean of the values. Option D: COUNT function counts how many cells contain numbers. Option C: MAX function returns the maximum (largest) value from a range of cells. Since the question asks for the largest value, the MAX function is the correct choice. The syntax =MAX(A1:A10) will examine all cells from A1 to A10 and return the highest number among them. Therefore, the correct answer is C.
