2. Compound Interest Calculation
A farmer deposited Rs. 3,00,000 in a development bank for 2 years to get half-yearly compound interest at 10% per annum. After one year, the bank changed the policy and decided to calculate the interest terminally at the same rate.
Answer the following:
a. Find the interest of the first year after deducting 5% tax. [1]
