Answer 1

Below are the steps to find the answer:

Assume each row represents the one unit of order.

Take the data in an excel sheet

Select the dataset and insert pivot table

In the pivot field place Customer id in a row

Product name to be placed in Values and set the field value to count of product name

Place City in the row field

Go to the table design and in report layout select show in tabular form

In subtotals, select don't show subtotal

Then you will get the three columns of data which is Customer id, City Name and Count of orders like this

customer_id	City	Count of product_name
71041	San Diego	1
103289	Los Angeles	1
107746	Los Angeles	1
157441	San Francisco	1
158646	San Diego	1
178843	Miami	1
179297	Philadelphia	1
182439	San Francisco	1

Select the data and paste in another sheet

Sort the product name from highest to lowest

you will get the customer Id with the highest number of orders and the city name.
