Answer 1

Please use below code:
public function getDisplayPrice($product) {
if($product->getFinalPrice()) {
return $product->getFormatedPrice();
} else if ($product->getTypeId() == Mage_Catalog_Model_Product_Type::TYPE_BUNDLE) {
$optionCol= $product->getTypeInstance(true)
->getOptionsCollection($product);
$selectionCol= $product->getTypeInstance(true)
->getSelectionsCollection(
$product->getTypeInstance(true)->getOptionsIds($product),
$product
);
$optionCol->appendSelections($selectionCol);
$price = $product->getPrice();
foreach ($optionCol as $option) {
if($option->required) {
$selections = $option->getSelections();
$minPrice = min(array_map(function ($s) {
return $s->price;
}, $selections));
if($product->getSpecialPrice() > 0) {
$minPrice *= $product->getSpecialPrice()/100;
}
$price += round($minPrice,2);
}
}
return Mage::app()->getStore()->formatPrice($price);
} else {
return "";
}
}

Answer 2

I solved it by own method, not sure its acceptable or not.
$bundle_option = Mage::app ()->getRequest ()->getParam('bundle_option');
$bundle_option_array = call_user_func_array('array_merge', $bundle_option);
$price = Mage::Helper('airhotels/bundle')->getBundlePrice($productid,$bundle_option_array);
my helper file is
public function getBundlePrice($productId,$bundle_option_array) {
$product = new Mage_Catalog_Model_Product();
$product->load($productId);
$price=0;
$selectionCollection = $product->getTypeInstance(true)->getSelectionsCollection($product->getTypeInstance(true)->getOptionsIds($product), $product);
foreach($selectionCollection as $option)
{
if (in_array($option->getSelectionId(), $bundle_option_array)){
$price += $option->price;
}
}
return $price;
}
