Well, I will not directly solve your question but I will help you in solving. I will inbox you soon.
Firstly, you can do it either by direct method or by step deviation method.
In case of direct method, mean = summation fx × summation fi
In case of step deviation method, mean = a+ summation fiui ÷ fi × h. (where ui = di - a/h)
