Final answer:
Errors in the unadjusted trial balance will result in higher debits or credits by specific amounts.
Step-by-step explanation:
a. Purchase of Land and Building:
Debit to Land: $12,000
Debit to Cash: $25,000
Credit to Building: $13,000
Here, the total debits are $12,000 (Land) + $25,000 (Cash) = $37,000, and the total credits are $13,000 (Building).
The debits are higher by $37,000 - $13,000 = $24,000. Therefore, debits will be higher on the unadjusted trial balance.
b. Incorrect Credit to Rent Revenue:
Incorrect Credit to Rent Revenue: $1,300
This error results in an overstatement of Rent Revenue. Since Rent Revenue is a revenue account with a normal credit balance, this error causes credits to be higher by $1,300 on the unadjusted trial balance.
c. Mismatch in Accounts Receivable and Sales:
Debit to Accounts Receivable: $4,500
Credit to Sales: $450
The total debits are $4,500 (Accounts Receivable) and the total credits are $450 (Sales).
Debits are higher by $4,500 - $450 = $4,050. Therefore, debits will be higher on the unadjusted trial balance.
In summary:
For error (a), debits will be higher by $24,000.
For error (b), credits will be higher by $1,300.
For error (c), debits will be higher by $4,050.
