i got everything exce[t x 5? why x 5?
we have different class widths of diff sets of values :)
So the 11.5 is done by multiplying it with 5, to make it a common.. .
got it?
to make something in common in class width they multiplied it with 5
otherwise it should have been 115/2 = 57.5 cm

to make common in class width :)

DUde.
To find the length for 115 frequency thing,

Length is found by frequency density formula... so f.d. = frquency/class width
                                                                                  115/2 = 57.5  but they said it is 11.5
                                                        if we do like this   115/2 x 5  that will give 11.5
so they multiplied it with 5
