The minimum amount at which the forfeited shares can be reissued as fully paid-up must cover the unpaid amount on the shares.
Step 1: Calculate the unpaid amount per share:
Unpaid amount = Final call not paid = \rupee 2 per share.
Step 2: Total unpaid amount for all shares:
\[
\text{Total unpaid amount} = 5,000 \times \rupee 2 = \rupee 10,000
\]
The shares can be reissued at a minimum price of \rupee 10,000 to cover the unpaid call amount.
