Answer:
Dr Income Summary account 90,000
Cr Capital account, E. Duffy 60,000
Cr Capital account, J. Gladwin 30,000
Explanation:
The income summary account has a credit balance, and in order to close it we must debit it against capital accounts.
Since Duffy was entitled to 2/3 of the profits, then he should receive $60,000, and the remaining $30,000 would go to Gladwin.
