    Number of students getting at least 60% marks in Chemistry     = Number of students getting 30 and above marks in Chemistry     = 21. Number of students getting at least 40% marks in aggregate     = Number of students getting 20 and above marks in aggregate     = 73. Required percentage = 21 x 100 % 73 = 28.77% 29%.
