Use following code:-
public function getBestSellersCollection($numDays = 60, $categoryId)
{

                $todayDate = Mage::getModel('core/date')->date('Y-m-d');
                                $fromDate = date('Y-m-d', strtotime('now -'.$numDays.' days'));

                                $_bestSellersCollection = Mage::getResourceModel('reports/product_collection')
                                ->addOrderedQty()
                                ->setStoreId($storeId)
                                ->addAttributeToSelect('name')
                                ->addAttributeToSelect('entity_id')
                                ->addAttributeToSelect('url_path')
                                ->addCategoryFilter($categoryId)
                                ->addAttributeToFilter('created_at', array('date' => true, 'from' => $fromDate, 'to' => $todayDate))
                                ->setOrder('ordered_qty', 'desc');
                                $bestsoldids = Array();
                                foreach($_bestSellersCollection as $col){
                                                $bestsoldids[] = $col->getData('entity_id');
                                }
                                return $bestsoldids;
    }
