Looking at the forfeiture and re-issue details:
Understanding what was received before forfeiture:
Face value per share = Rs. 100
Amount not paid (second and final call) = Rs. 30 per share
Amount already received per share = Rs. 100 - Rs. 30 = Rs. 70 per share
For the 150 shares re-issued:
Amount in Share Forfeiture Account for these 150 shares = 150 × Rs. 70 = Rs. 10,500
Re-issue price per share = Rs. 60
Since shares are re-issued at Rs. 60 against face value of Rs. 100, there is a discount of Rs. 40 per share.
Loss on re-issue for 150 shares = 150 × Rs. 40 = Rs. 6,000
This loss is debited to Share Forfeiture Account.
Capital Reserve calculation:
Capital Reserve = Amount in Share Forfeiture A/c (for re-issued shares) - Loss on re-issue
Capital Reserve = Rs. 10,500 - Rs. 6,000 = Rs. 4,500
The forfeited amount relating to re-issued shares, after adjusting for the loss on re-issue, is transferred to Capital Reserve.
Answer: Option 2: Rs. 4,500
