On the basis of the above information answer the question.

Share capital will be debited by face value of shares forfeited i.e., 3000×₹10=₹30,000
Share 1st call amount is due but not received hence, it will be credited by 3000×₹2=₹6,000
Share final call amount is due but not received hence, it will be credited by 3,000×₹1=₹3,000
Share forfeiture account will be credited by actual amount received on forfeited share i.e., 3,000×7=₹21,000
When a company re-issues forfeited shares and gains arise from the transaction, these gains are typically transferred to the "Capital Reserve Account." Capital reserves are used to account for profits that do not arise from day-to-day operations, such as gains on re-issuing forfeited shares.
Amount received on re-issue of shares=3,000×8=₹24,000
According to "Table F" of the Companies Act, 2013, the rate of interest on calls in advance is typically set at 12% per annum. This provision ensures that shareholders who pay their calls in advance are entitled to receive interest on the amount paid in advance at this specified rate.
