Solution

The correct option is C
200-300

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

$M e d i a n t e r m = (\frac{n}{2})$ = $\frac{188}{2} = 94^{t h} t e r m$

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