1. Given Data:
- Provision for tax on 1st April 2022 = rupee 10,000
- Provision for tax on 31st March 2023 = rupee 25,000
- Tax paid during the year = rupee 15,000
2. Formula to Calculate Provision for Tax to be Added:
\[
{Provision to be added} = {Tax paid} + {Increase in provision}
\]
3. Increase in Provision:
\[
= rupee 25,000 - rupee 10,000 = rupee 15,000
\]
4. Total Provision to be Added:
\[
= rupee 15,000 + rupee 15,000 = rupee 30,000
\]
Thus, the amount of provision for tax to be added is rupee 30,000 (Option A).
