Solution

The correct option is C 200-300
$\begin{matrix} W e e k l y w a g e s (₹) & N o . O f w o r k e r s & C u m u l a t i v e f r e q u e n c y 0 - 100 & 40 & 40 100 - 200 & 39 & 79 200 - 300 & 34 & 113 300 - 400 & 30 & 143 400 - 500 & 45 & 188 \end{matrix}$

$M e d i a n t e r m = \frac{(\frac{n}{2}) + (\frac{n}{2} + 1)}{2} = \frac{(94 + 95)}{2} = {94.5}^{t h} t e r m$

94.5 falls between 79 and 113, i.e. in the class 200-300.
So, the median class is 200 - 300.
