Answer
(i) The formula in E9 is = AVERAGE (C9 : D9). It calculates the average of the marks in cells C9 and D9. It uses the AVERAGE() function.
(ii) When the formula is copied to cells from E5 to E11, the cell references adjust themselves relatively as follows:
E5 = AVERAGE (C5 : D5)
E6 = AVERAGE (C6 : D6)
E7 = AVERAGE (C7 : D7) and so on.
(iii) The maximum value can be calculated by using the formula =MAX(E5:E11). The maximum value is 93.
The minimum value can be calculated by using the formula =MIN(E5:E11). The minimum value is 66.5.
(iv) Ravi can use the formula =AVERAGE(C5:C11) in the cell C12 to calculate the average of Oral marks.
He can use the formula =AVERAGE(D5:D11) in the cell D12 to calculate the average of Written marks.
