Answer 1

${}{ \huge{ \boxed{ \purple{solution - }}}} \\ \bf\ formula \: used - \\ mode = l + (\frac{f1 - f0}{2f1 - f0 - f2} ) \times c$

Where,

l = lower limit of the modal class = 200

f0 = frequency of the class preceding the modal class = 18

f1 = frequency of the modal class = 27

f2 = frequency of the class succeeding the modal class = 20

c = size of class interval (the class intervals are same) = 100

∴ Substituting the values l = 200, f0 = 18, f1 = 27, f2 = 20 and c = 100 in the formula of mode. We get,

Mode= 200(27+18)/2×27-18-20 ×100

=200+225/4

=200+56.5

=256.25
