Hello,

CBSE has already prescribed formula to convert the CGPA in to percentage of marks. You can find the formula to convert the CGPA into percentage on the class 10th certificate. You have to multiply 9.5xCGPA to calculate the percentage and you have to fill the same in CAT application form. The CGPA should be multiplied with 10 in case the formula for conversion of CGPA in to percentage is not prescribed by a board/university.
