Amount due to Kiara on retirement (1-4-2023) = Rs 5,00,000.
Payment schedule: Two yearly instalments of Rs 2,50,000 each, plus interest @ 10% p.a. on the unpaid balance.
The first instalment is paid on 31-03-2024 (one year after retirement).
1. Calculate Interest for the first year (1-4-2023 to 31-03-2024):
Interest is calculated on the outstanding balance at the beginning of the year.
Outstanding Balance on 1-4-2023 = Rs 5,00,000.
Interest for Year 1 = Outstanding Balance \( \times \) Rate \( \times \) Time
\[ \text{Interest}_1 = 5,00,000 \times \frac{10}{100} \times 1 = Rs 50,000 \]
2. Calculate the total amount of the first instalment:
First Instalment = Principal Amount + Interest for Year 1
\[ \text{First Instalment} = 2,50,000 + 50,000 = Rs 3,00,000 \]
This payment is made on 31-03-2024.
