In a food processor, mix all-purpose flour, whole-wheat flour, yeast, salt, and sugar. Now measure hot water and oil and combine them into a bowl. When food processor is mixing (while running), add slowly hot water and oil mixture until the mixture becomes smooth. Sometimes it seems dry after adding all hot water and oil mixture. If it happens then add two or more hot water teaspoons till the mixture is soft and smooth. After that get the mixture out and process kneads for 1 minute.
