Options

A. Rs 21704
B. Data inadequate
C. Rs 23220
D. Rs 20188

Answer

To find the sales on Sunday, we will follow these steps:

### Step 1: Calculate the total sales for the six days (Tuesday to Sunday)
The average sales per day for the remaining six days of the week is given as Rs 15640. To find the total sales for these six days, we multiply the average by the number of days:

\[ \text{Total sales for six days} = \text{Average sales} \times \text{Number of days} = 15640 \times 6 \]

Calculating this gives:

\[ \text{Total sales for six days} = 15640 \times 6 = 93840 \]

### Step 2: Calculate the total sales for Tuesday to Saturday
The average sales from Tuesday to Saturday is given as Rs 14124. We will calculate the total sales for these four days:

\[ \text{Total sales for Tuesday to Saturday} = \text{Average sales} \times \text{Number of days} = 14124 \times 5 \]

Calculating this gives:

\[ \text{Total sales for Tuesday to Saturday} = 14124 \times 5 = 70620 \]

### Step 3: Calculate the sales on Sunday
Now, we can find the sales on Sunday by subtracting the total sales from Tuesday to Saturday from the total sales for the six days (Tuesday to Sunday):

\[ \text{Sales on Sunday} = \text{Total sales for six days} - \text{Total sales for Tuesday to Saturday} \]

Substituting the values we calculated:

\[ \text{Sales on Sunday} = 93840 - 70620 \]

Calculating this gives:

\[ \text{Sales on Sunday} = 23220 \]

### Final Answer
The sales on Sunday is Rs 23220.
