Hello
excuse me if i sent your answer now
i think your answer obtain via this way that you should compute diffrence of Qd and mean then you sould use proportion
for example you have d percent and median persent and diffrence of Qd and mean so you can find diffrence of mean and Q2 then you
can use itto add to mean and will obtain Q2
it is the same for Q1 or Q3 .....
I have you be succeed
best regards
