linq query with the desired result

First of all thanks to Mark and Bob,
 
After their comments I went through the problem again and found it so simple,
so those who might be in trouble for them I am posting the answer what it worked for me.
 
I am having my data in the datatable "dt".
Firstly I have grouped the 'Type' and collected result in some variable.
 
var str = (from d in dt.AsEnumerable()
               group d by d["Type"] into m
               select new { Type = m.Key, Can = m });
 
Now here what actually happens is, the 'Type' in the datatable I am getting in Type property and the remaining data in Can property.
              
Once I group my data according to 'Type', then its simple to get the count.
 
//get the customers count with Type "CK"
int CntCK = str.ToArray()[0].Can.Where(c => c.ItemArray[0].ToString() != "").Select(c => c.ItemArray[0].ToString()).Count();
 
//get the reservation count with Type "CK"
int ResCntCK = str.ToArray()[0].Can.Where(c => c.ItemArray[3].ToString() != "").Select(c => c.ItemArray[3].ToString()).Count();
 
//get the amount of "CK" customer
var arrAmountCK = grpOfOfferType.ToArray()[0].Can.ToArray().Select(c => c.ItemArray[4].ToString());
double AmountCK = Convert.ToDouble(arrAmountCS.ToArray()[0]);
 

This is how I broke the it into parts and got the result.
Thanks All,
Stone
