Let's see example with output:

Category Model:

<?php
  
namespace App\Models;
  
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Category extends Model
{
    use HasFactory;

     */
    public function products()
    {
        return $this->hasMany(Product::class);
    }
}

Product Model:

<?php
  
namespace App\Models;
 
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;
  
class Product extends Model
{
    use HasFactory;
  
    protected $fillable = [
        'name', 'price'
    ];
}

withMin() Example:

<?php
  
namespace App\Http\Controllers;
  
use App\Models\Category;
  
class SignaturePadController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $categories = Category::select("id", "name")
                        ->withMin('products', 'price')
                        ->get()
                        ->toArray();
 
        dd($categories);
    }
}

Output:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => Mobile
            [products_min_price] => 100
        )
    [1] => Array
        (
            [id] => 2
            [name] => Laptop
            [products_min_price] => 200
        )

withMax() Example:

<?php
  
namespace App\Http\Controllers;
  
use App\Models\Category;
  
class SignaturePadController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $categories = Category::select("id", "name")
                        ->withMax('products', 'price')
                        ->get()
                        ->toArray();
 
        dd($categories);
    }
}

Output:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => Mobile
            [products_max_price] => 120
        )
    [1] => Array
        (
            [id] => 2
            [name] => Laptop
            [products_max_price] => 210
        )
)

withAvg() Example:

<?php
  
namespace App\Http\Controllers;
  
use App\Models\Category;
  
class SignaturePadController extends Controller
{
    /**
     * Write code on Method
     *
     * @return response()
     */
    public function index()
    {
        $categories = Category::select("id", "name")
                        ->withAvg('products', 'price')
                        ->get()
                        ->toArray();
 
        dd($categories);
    }
}

Output:

Array
(
    [0] => Array
        (
            [id] => 1
            [name] => Mobile
            [products_avg_price] => 110.0000
        )
    [1] => Array
        (
            [id] => 2
            [name] => Laptop
            [products_avg_price] => 205.0000
