Subscription share = (10000×15.50)/1.00+(20000× 4.50)/1.00 = 245,000 copies.

Subscription commission = 245,000×1.0% = 2,450 yuan.

Investors subscribed for 245,000 fund shares and paid an additional subscription commission of 2,450 yuan.

Assuming that the investor chooses the fund share to pay the subscription commission, the investor finally subscribes for the share:

Net subscription share = 245000-2450 = 242550.
