A Correct answer
Explanation

The company collected 80% of needed amount at Rs. 400 per partner, so these partners represent 50% of total partners (since 80% of amount from 50% of partners means each remaining partner must give Rs. 100 to reach 100%). If 50% partners gave 400 each (80% of total), remaining 50% need to give 20% of total at Rs. 100 each.
