To determine the equated monthly instalments (EMI) in the case that Jain opts to buy the apartment, we can use the annual loan amortization schedule provided in Exhibit 1.

The loan amount is ₹10,000,000 and the interest rate is 10.25% per year, based on monthly compounding. The loan term is 20 years.

Using the annual loan amortization schedule, we can calculate the principal and interest components of each year’s payment. For example, in the first year, the principal component is ₹160,367 and the interest component is ₹1,017,605.

To convert the annual payments to monthly payments, we can divide each year’s payment by 12. For example, in the first year, the monthly payment would be (₹160,367 + ₹1,017,605)/12 = ₹93,305.

Therefore, the equated monthly instalment (EMI) in the case that Jain opts to buy the apartment is ₹93,305.
