A share of $\text{Rs. }10$ on which $\text{Rs. }8$ was called up was forfeited for non-payment of $\text{Rs. }5$. This share can be reissued at a minimum price of $\text{Rs.}$:

Let's calculate the relevant values:Called-up Value = $\text{Rs. }8$ Unpaid / Arrears = $\text{Rs. }5$ Paid-up amount (Amount forfeited) = $\text{Called-up}-\text{Unpaid}=8-5=\text{Rs. }3$ The maximum discount a company can grant during the reissue of a forfeited share is equal to the amount already received on that share, which is $\text{Rs. }3$. Assuming the reissued share is made fully paid-up ($\text{Rs. }10$):
$$\text{Minimum Reissue Price}=\text{Fully Paid-up Value}-\text{Maximum Permissible Discount}$$
$$\text{Minimum Reissue Price}=10-3=\text{Rs. }7$$
