var data = new[] {
 new { Id = 0, Cat = 1, Price = 2 },
 new { Id = 1, Cat = 1, Price = 10 },
 new { Id = 2, Cat = 1, Price = 30 },
 new { Id = 3, Cat = 2, Price = 50 },
 new { Id = 4, Cat = 2, Price = 120 },
 new { Id = 5, Cat = 2, Price = 200 },
 new { Id = 6, Cat = 2, Price = 1024 },
};

var ranges = new[] { 10, 50, 100, 500 };

Needed output is grouped price count by equal or greater than the range used according categories.
(in one linq statement)

cat    range       count
-------------------------------------
1       10           2    (In 1. categories there is 2 item that price >= 10(range) [10;30]) 
2       10           4    (In 2. categories there is 4 item that price >= 10(range) [50;120;200;1024]) 
2       50           4    ....
2      100           3    ....
2      500           1    (In 2. categories there is 1 item that price >= 500(range) [1024])

    Try this:

    var data = new[] {
 new { Id = 0, Cat = 1, Price = 2 },
 new { Id = 1, Cat = 1, Price = 10 },
 new { Id = 2, Cat = 1, Price = 30 },
 new { Id = 3, Cat = 2, Price = 50 },
 new { Id = 4, Cat = 2, Price = 120 },
 new { Id = 5, Cat = 2, Price = 200 },
 new { Id = 6, Cat = 2, Price = 1024 },
};

var ranges = new[] { 10, 50, 100, 500 };

var result = from r in ranges
        from g in data
        where g.Price >= r
        select new {g.Cat, Price=r};

var groupedData = 
        from d in result
        group d by new{d.Cat, d.Price} into g
        select new{Cat=g.Key.Cat, Price=g.Key.Price, TotalCount=g.Count()};
