Answer :
Sure! Let's address the questions one by one, showing the process clearly:
(क) Write the number of sales of mobiles of Stall-A in series form:
For Stall-A, the sales over the first few days are given as 20, 25, 30, and so on. So, in series form, this looks like:
[tex]\[ 20, 25, 30, \ldots \][/tex]
This pattern suggests that the sales might be increasing by 5 each day. However, we only need to list the specific sales in the given series for the first few days, as shown above.
(ख) How many total mobiles did Stall-A sell in a week? Find it:
To find the total sales by Stall-A in a week, we consider the sales for each day. Assuming the sales continue to increase by 5 each day beyond the first three days given, the sales for a full week (7 days) would be:
[tex]\[ 20, 25, 30, 35, 40, 45, 50 \][/tex]
So, the total sales for the week is:
[tex]\[ 20 + 25 + 30 + 35 + 40 + 45 + 50 = 245 \][/tex]
(ग) Compare the sales of mobile phones sold by the stalls in a week:
Now, let's compare the weekly sales of both stalls:
- Stall-A sold a total of 245 mobiles over the week.
For Stall-B, the sales pattern observed for the first few days is 3, 6, 12, and so on. This suggests that the sales might be doubling each day. Extending this pattern for 7 days, Stall-B's sales are:
[tex]\[ 3, 6, 12, 24, 48, 96, 192 \][/tex]
Adding them up gives a total for Stall-B:
[tex]\[ 3 + 6 + 12 + 24 + 48 + 96 + 192 = 381 \][/tex]
Therefore, in a week:
- Stall-A sold 245 mobiles,
- Stall-B sold a total of 381 mobiles.
Hence, Stall-B sold more mobiles compared to Stall-A over the week.
