We have to interpret the graph very well.
The graph histogram shows that initially increase the decrease towards end. This particular pattern denoted as positively skewed distribution.
There is some facts about the central tendency that is for positively skewed distribution, Mean>Median>Mode.
So here Mean must be less than median.
Now task is to find probably where to median lies.
If we sum first two bars which is below 80, we get, 15%+40%=55%
Which is more than 50% hence median must lie below 80 and more than 75.
So correct answer is median lies 75 to 80 and mean greater than median.
