If the Journal is a diary where you write everything as it happens, the Ledger is a set of folders. Each folder (Account) contains only transactions related to one specific person, asset, or expense.
Definition:
A Ledger is the “Principal Book of Accounts” where transactions are classified and summarized into individual accounts.
Format of ledger
Think of a Ledger as a “Money Diary” for one specific person or thing.
- Left Side (Debit – Dr): Think of this as the “Incoming” or “Receiver” side.
- Right Side (Credit – Cr): Think of this as the “Outgoing” or “Giver” side.

|---|---|---|---|---|---|---|---|
| LEFT SIDE (DEBIT) | Start with “To“ | RIGHT SIDE (CREDIT) | Start with “By“ |

Answer Key (The Step-by-Step Solution)
For each sum, I will show you which two accounts are affected and where the money goes.
Sum 1: Capital Entry
- Accounts affected: Cash A/c and Capital A/c.
- The Logic: Cash comes in (Debit), Capital is the source (Credit).
Cash Account

|---|---|---|---|---|---|
| April 1 | To Capital A/c | 2,00,000 |
Sum 2: Asset Purchase

Furniture Account
| Date | Particulars | Amount (₹) | Date | Particulars | Amount (₹) |
|---|---|---|---|---|---|
| April 5 | To Cash A/c | 20,000 |
Sum 3: Credit Purchase (The “Liability”)
- Accounts affected: Purchases A/c and Modern Traders A/c.
- The Logic: Goods come in (Debit), Modern Traders is the Giver/Creditor (Credit).
Modern Traders Account
| Date | Particulars | Amount (₹) | Date | Particulars | Amount (₹) |
|---|---|---|---|---|---|
| April 10 | By Purchases A/c | 15,000 |
Sum 4: Credit Sale (The “Asset/Debtor”)
- Accounts affected: Kiran’s A/c and Sales A/c.
- The Logic: Kiran is the Receiver (Debit), Sales is the Income (Credit).
Kiran’s Account
| Date | Particulars | Amount (₹) | Date | Particulars | Amount (₹) |
|---|---|---|---|---|---|
| April 15 | To Sales A/c | 25,000 |
Sum 5: Paying a Creditor
- Accounts affected: Modern Traders A/c and Cash A/c.
- The Logic: Modern Traders receives money (Debit), Cash goes out (Credit).
Modern Traders Account (Updated)

|---|---|---|---|---|---|
| April 20 | To Cash A/c | 10,000 | April 10 | By Purchases A/c | 15,000 |
| Balance c/d | 5,000 | ||||
| Total | 15,000 | Total | 15,000 |
(Note: The “Balance c/d” shows we still owe them ₹5,000).
Tips and tricks
5 simple “Golden Tricks” to master ledger posting without any confusion:
- The “Opposite Name” Trick
Inside any account, never write its own name. If you are in the Cash Account, look at the journal and grab the other name (like Sales or Rent) and write that instead. It’s like a “No Selfies” rule! - The “To” & “By” Shortcut
Remember: “To” is Left, “By” is Right.
If the journal entry has a “To” (the credit part), it ironically moves to the Left side of the other account. If it’s the top name (the debit part), it moves to the Right side of the other account using “By.” - The Cash “Plus/Minus” Hack
For Cash or Bank accounts:- Left side is your (+) Plus side (Money coming in).
- Right side is your (-) Minus side (Money going out).
If you paid someone, it’s always on the Right. If you received money, it’s always on the Left.
- The “Best Friends” Rule (Discounts)
Cash and Discount are best friends; they always stay on the same side. If you post Cash on the Left side, the Discount Allowed goes on the Left side too. They never leave each other. - The “Slide” Balancing Trick
When finishing an account, the “Balance c/d” is just a gap-filler on the smaller side. To start the next month, just “Slide” that amount to the opposite side below the total line and call it “Balance b/d.” That is your real final answer.
