While evaluating CA CPT papers an examiner has escaped the marks of one of the student while calculating the result summary of his class. However he knew that the average marks of the class was $72\%$ and the marks of the remaining students were $56, 85, 78, 70, 75, 48, 65, 85$ and $75$. The marks of the student were __________.
