1.Write a query to find the average order value for all Customers.

db.coustomer.find().aggregate(field_name).sort()

db.customer.find({months:{$lt:10}};

db.checkdate.find( { status: "delivery",estimated_delivery: new ISODate("2012-05-17T08:14:15.656Z") });

3.Query your database to find the sum of all orders received in this month

db.orders.find({$groupby:[{$max:"orders"},{"customer_date"<40}]});

4.Query your database to find customers count in various cities, group them by names of cities
