We can draw the table for better understanding.

$\begin{array}{lll} & \textbf{S} & \textbf{M} \\ \text{Cost price:} & 90x & 100x \\ \text{Delivery charge:} & ₹\;150 & ₹\;0 \end{array}$

A person bought the items from the store $\text{S}$ and saved  $₹\;100$.

So, $90x + 150  = 100x – 100$

$\Rightarrow -10x = -250$

$\Rightarrow {\color{Blue}{\boxed{x = 25}}}$

$\therefore$  The price of the item at the online store $\text{S}$, if there are no other charges includes $ = 90x = 90 \times 25 = ₹\;2250.$

Correct Answer $:\text{B}$
