Write the format of the functions used in MS Excel to perform the following tasks:

To determine the lowest value of the cell references from A4 to A12.

Write the format of the functions used in MS Excel to perform the following tasks:

To find the sum of all the prime numbers from 1 to 10.

Spot the error in each of the following:

1. =SUM ('C9':C14)
2. =$B*$3*C$
3. =COUNT(9, 12, 17, 26, A$)
4. =AVERAGE(A1:An)/n
5. =MAX('19', 70, 101)
6. =ADD(24+54+77-38)

Given below is a table containing 'Rate/gm' and 'Wt in gm' in columns A and B respectively. Cell D1 contains GST as 5% (i.e. 0.05). The cost (including GST) of each item is to be calculated and stored in the corresponding cells of column C as (Rate/gm) * Wt in gm * GST.

Based on the above case, answer the following questions:

(a) Which of the following represents cell D1 as absolute?

1. $D1$
2. D$1$
3. $D$1
4. D1$

(b) What will happen when cell C1 is absolute and used in the formula to find cost in the cells from C4 to C7?

1. All cell values from C4 to C7 will become 0 (zero).
2. The cell value D1 will be shifted into the cell C1.
3. The cell value D1 will be copied into the cell C1.
4. All the cell values from C4 to C7 will occupy same non-zero values.

(c) What will be the formula to calculate the cost in column C4?

1. A4 * B4 * D1
2. A4 * B4 * $D$1
3. A4 * $B4$ * D1
4. $A4$ * $B4$ * $d4$

(d) What will be the formula to calculate the cost in column C7?

1. $A$7 * B7 * D1
2. A7 * B7 * $D$1
3. A$7$ * B$7$ * D1
4. A7 * B7 * $D1$
