Hy mate_❤

n=7(odd)

Data in ascending order:- 8,12,16,10,30,20,40

Upper Quartile = (n+1)/4 th observation

= (7+1)/4 th observation

= 8/4 th observation

= 2 th observation

= 12 (Answer)

Lower Quartile = 3(n+1)/4 th observation

=3(7+1)/4 th observation

= 3×8/4 th observation

= 24/4 th observation

= 6 th observation

= 20 (Answer)
