Step 1 (Extract interest on loans data from table).
From the table:
1998 = 23.4 lakhs
1999 = 32.5 lakhs
2000 = 41.6 lakhs
2001 = 36.4 lakhs
2002 = 49.4 lakhs
Step 2 (Find total interest over all years).
Total = \(23.4 + 32.5 + 41.6 + 36.4 + 49.4\)
First, \(23.4 + 32.5 = 55.9\)
Next, \(55.9 + 41.6 = 97.5\)
Then, \(97.5 + 36.4 = 133.9\)
Finally, \(133.9 + 49.4 = 183.3\) lakhs
Step 3 (Calculate average per year).
Number of years = 5
Average interest = \(\dfrac{183.3}{5} = 36.66\) lakhs
Step 4 (Match with options).
This matches Option 4, not Option 2.
\[
\boxed{\text{Rs. 36.66 lakhs (Option (d)}}
\]
