SQL Puzzle | The OrdersAndState puzzle

We need to find out customers who have placed orders in 2017 and for those orders the amount should be equal or greater than $100.
Note that if it has multiple orders all must be at least $100 and the order must be going to IL. Also If there are multiple orders that meet 1 and 2 then all must be going to IL

Please check out the sample input values and sample expected output below.

Sample Input

Customerid OrderDate State Orderamount
1 2016-11-02 00:00:00.000 IL 100
2 2017-02-05 00:00:00.000 IL 200
3 2017-06-05 00:00:00.000 WI 200
3 2017-05-15 00:00:00.000 WI 200
1 2017-03-02 00:00:00.000 IL 100
