I have searched more and got a solution, it's not a good idea to change core file but it's working. You can calculate price with charges before sending in google checkout. change core file of google checkout at /app/code/core/Mage/GoogleCheckout/Model/Api/Xml/checkout.php .

Go to line 579 and make condition as you want. In my case the condition is as:

*********************

$subTotal = Mage::getModel('checkout/cart')->getQuote()->getSubtotal();
            if($subTotal <=68.50){

            $xml .= <<<EOT
                <{$nodeName} name="{$title}">
                    <shipping-restrictions>
                        <allowed-areas>
                        {$allowedAreasXml}
                        </allowed-areas>
                    </shipping-restrictions>
                    <price currency="{$this->getCurrency()}">{$price}</price>
                </{$nodeName}>
EOT;
            }

            if(($subTotal > 68.50) && ($subTotal < 75)){
            $price = $subTotal*10/100;
            $xml .= <<<EOT
                <{$nodeName} name="{$title}">
                    <shipping-restrictions>
                        <allowed-areas>
                        {$allowedAreasXml}
                        </allowed-areas>
                    </shipping-restrictions>
                    <price currency="{$this->getCurrency()}">{$price}</price>
                </{$nodeName}>
EOT;
            }

            if($subTotal >=75){
            $price = 0.00;
            $xml .= <<<EOT
                <{$nodeName} name="{$title}">
                    <shipping-restrictions>
                        <allowed-areas>
                        {$allowedAreasXml}
                        </allowed-areas>
                    </shipping-restrictions>
                    <price currency="{$this->getCurrency()}">{$price}</price>
                </{$nodeName}>
EOT;
            }
        }

Now refresh your store and make payment with google checkout.
