Explanation:

- The company issued 4,000 shares, requiring Rs4 per share on the first call, totaling Rs16,000.

- There were applications for 13,000 shares, but 3,000 applications were rejected.

- Excess application money from the remaining 10,000 applications is used to cover allotment and calls.

- The excess money (10,000 shares - 4,000 shares allotted = 6,000 shares with Rs3 each, totaling Rs18,000)

Excess Money 6,000 X 3 = 18,000

 Allotment Adjusted 4,000 X 2 =  8,000  money left 18,000 - 8,000 = 10,000

Call money to be received 4,000 X 4 = 16,000

Excess money Adjusted =  10,000 

Money to be received Rs 6,000
