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
