Concept:
Sometimes, at the time of death or retirement of a partner, the partners decide:
• not to change the book values of assets and liabilities,
• but still give the retiring/deceased partner his share of revaluation profit or loss.
In such cases:
• Memorandum Revaluation Account is prepared,
• or adjustment entry is passed without changing actual asset values.
The deceased partner must receive his share of hidden profit or appreciation.
Therefore:
• Deceased Partner's Capital Account is credited,
• and gaining partners compensate him.
The compensation burden is borne by the partners who gain from his sacrifice.
Hence adjustment is made in:
\[
\text{Gaining Ratio}
\]
Step 1: Understanding why deceased partner is credited.
Suppose assets have appreciated.
The deceased partner is entitled to his share in this appreciation because:
• the increase in asset value arose before his death,
• therefore it a profit belonging partly to him.
Hence:
\[
\text{Deceased Partner's Capital A/c is credited}
\]
Step 2: Who bears this adjustment?
After death, continuing partners enjoy the increased future benefit.
Therefore:
• partners who gain in future profit-sharing ratio,
• should compensate the deceased partner.
Thus:
\[
\text{Gaining Partners' Capital Accounts are debited}
\]
Step 3: Basis of adjustment.
The adjustment is made according to:
\[
\text{Gaining Ratio}
\]
because only the partners who gain extra share should bear the compensation.
Step 4: Evaluating all options.
Option (A):
\[
\text{credited; debited; Old Ratio}
\]
Incorrect because adjustment is not in old ratio.
Option (B):
\[
\text{debited; credited; New Ratio}
\]
Incorrect because deceased partner should receive benefit, not loss.
Option (C):
\[
\text{credited; debited; Gaining Ratio}
\]
Exactly correct.
Option (D):
\[
\text{debited; credited; Sacrificing Ratio}
\]
Incorrect because gaining partners compensate the deceased partner.
Final Conclusion:
Therefore:
\[
\boxed{
\text{Deceased Partner's Capital A/c is credited and Gaining Partners'
Capital A/cs are debited in gaining ratio}
}
\]
Hence, the correct answer is:
\[
\boxed{\text{(C)}}
\]
