Here is a online test question I worked on today:

Partnership net income or loss is allocated 60% to Cor and 40% to Eng. To form the partnership, Cor originally contributed assets costing $30,000 with a fair value of 60,000 on January 2, 2004, While Eng contributed $20,000 in cash. Drawing by the partners during the 2004 totaled $3000 by Cor and $9000 by Eng. Cor-Eng net income for 2004 was $25,000. Eng¡¯s initial capital account in Cor-Eng was?

A.     60,000 B. 40,000 C, 20,000 D. 25,000

I chosen C, but the answer is A. Can anyone explain?
