The upper Quartile is 75% of the graph and the lower quartile is 25% of the graph. Ask any question relating to these quartiles and i'll assist you accordingly, as until you dont get any question further explained regarding this topic you will find difficulties. You can also PM me, but make it quick!

i dont know if its 3/4 of the c.f or not but ill explain it here it is if ur cumulative frequency is 600 then the median is 300 upper quartile is calculate by adding half the median and lower quartile by subtracting half the median so upper quartile will be 450 chek it against the graph what comes and the lower quartile 150 check it against the graph as well the interquartile range is then calculated as upper quartile - lower quartile hope it helps
