Suppose you start with 0 rupees in your bank account, and then you have credits of ₹30, ₹40, and ₹50, and debits of ₹40, ₹50, and ₹60. What is your bank account balance now?
Starting balance: ₹0 Total credits: ₹30 + ₹40 + ₹50 = ₹120 Total debits: ₹40 + ₹50 + ₹60 = ₹150 Balance = Credits − Debits = ₹120 − ₹150 = −₹30 The bank account balance is −₹30 (a debit balance of ₹30).
Explanation
The chapter explains that credits are positive numbers and debits are negative numbers. The total balance is the sum of all credits and debits. Total credits = 30 + 40 + 50 = 120. Total debits = 40 + 50 + 60 = 150. Balance = 120 − 150 = −30.
Solution Steps
Step 1: Calculate total credits: 30 + 40 + 50 = 120
Step 2: Calculate total debits: 40 + 50 + 60 = 150
Step 3: Find balance: Total credits − Total debits = 120 − 150
Step 4: Result: −30 rupees
