in normal distribution,
median =means

and so median= (LQ+UQ)/2

using mean value find s.d

BOLD - How can this be possible ?

Take upper quartile as 75 % (probability of 0.75) OR lower quartile as 25 % (probability of 0.25). Though I recommend you to take 0.75 because for LOWER QUARTILE (0.25) you have to do a bit of more subtraction which will be confusing.
