Step 1: Adjust profits for abnormalities.
Abnormal losses depress profit and should be \emph{added back} to find normal maintainable profits.
\[
\begin{aligned}
\text{2019–20 (normal)} &= 40{,}000
\text{2020–21 (normal)} &= 46{,}000 + 3{,}000 = 49{,}000
\text{2021–22 (normal)} &= 52{,}000
\end{aligned}
\]
Step 2: Compute Average Profit (Simple Average).
\[
\text{Average Profit}=\frac{40{,}000+49{,}000+52{,}000}{3}
=\frac{1{,}41{,}000}{3}=47{,}000.
\]
Step 3: Apply Years’ Purchase.
Goodwill (Average Profit Method) \(=\) Average Profit \(\times\) Years’ Purchase
\[
\text{Goodwill}=47{,}000 \times 2 = 94{,}000.
\]
Note. The given “total capital Rs. 1,00,000” is \emph{not} required in the Average Profit Method (it would matter in Capitalisation/Super Profit methods).
Final Answer:
\[
\boxed{\text{Goodwill of the firm} = \text{Rs. }94{,}000}
\]
