If you pay Rs. 20 for an item costing Rs. 3.78, how much change do you...
Understanding the Cost and Payment
You paid Rs. 20 for an item that costs Rs. 3.78. To find out your change using the "All from 9 and the Last from 10" method, follow these steps:
Step 1: Calculate the Change
- Total amount paid: Rs. 20
- Cost of the item: Rs. 3.78
- Change = Amount Paid - Cost of Item = 20 - 3.78
Step 2: Using the "All from 9 and the Last from 10" Method
This method helps in quick subtraction. Here's how it works:
- For the rupee part (20 - 3):
- From 9, subtract the whole number part of the cost (3):
- 9 - 3 = 6
- For the paise part (20 - 0.78):
- First, convert 0.78 into paise (78 paise):
- 100 - 78 = 22 (this represents the last digit from 10)
Step 3: Combine the Results
- Now combine the results:
- You have Rs. 16 (from the rupee part) and Rs. 0.22 (from the paise part).
Final Calculation
- Add them together:
- 16 + 0.22 = 16.22
Therefore, the change you receive is Rs. 16.22, confirming that the correct answer is option 'A'.

If you pay Rs. 20 for an item costing Rs. 3.78, how much change do you...
From 10, apply the sutra to 3.78: 3 from 9 is 6, 7 from 9 is 2, 8 from 10 is 2, giving 6.22. Add Rs. 10: 6.22 + 10 = 16.22. So, the change is Rs. 16.22.
