No answer is 30
if you see the table from the photograph then n=11 , 11 is the odd number to find the median the formula is (n+1)/2 then we get (11 + 1)/ 2 and then we get 12/2 mm equals to 6 in the table the cumulative frequency which is just greater than 6 is 7 , the class belongs to 7 is 30 so the answer is 30
