firstly, find mean by using any of the formula below. then for finding mode and median it;s easier as the table is already prepared for mean,( i.e u could find from the table itself)
1. mean = Σfixi/Σfi

Mean = arithmetic sum of the data items / number of the data items given
median = is the value of that data item, such that half of the data items are more than or equal to its value. and, also, half of the data items are less than or equal to that value.
Mode = the most frequently occurring data item among all the data items.
there is a formula: mean - mode = 3 (mean - median)
this is given by Karl Pearson.
