Step 1: Applications received.
Shares applied = 70,000.
Shares issued = 50,000.
Therefore, excess applications = 20,000 shares.
Step 2: Application money per share.
Application = Rs. 5 (including premium).
Step 3: Excess money received.
Excess application = \( 20,000 \times 5 = Rs. 1,00,000 \).
Step 4: Adjustment of excess.
As per the passage, Rs. 40,000 was refunded and Rs. 60,000 was adjusted towards allotment.
Thus, in totality, the amount of excess application money accounted for = Rs. 1,00,000.
Final Answer: \[ \boxed{Rs. 1,00,000} \]
