I have applied for entry level data analyst role. Prepared for the interview with simplilearn. I got exactly same questions. I was sooo happy and confident. Just finished my interview a minute ago. Waiting for the result.

For question 42, I believe you should sum based off of the LineTotal instead of the UnitPrice. Reason being that you ask for total units sold greater than 1.5 million and each SalesOrderID could have multiple units of the same product in it. The unit price only picks up one of those units within each SalesOrderID while the LineTotal picks up the price of all units within that order. Line #2 of the sales order total table is an example, that order has 3 units of the same product ID and the unit price line only picks up one of those units. So the sql statement would be the same, just change SUM(sod.UnitPrice) to SUM(sod.LineTotal) in both the select and having statements.

Hi,
In question 33, why the query has the having clause avg(mkt_price)> 50 whereas the question asks for the average market price to be greater than 100?
Am I missing something?
