Actual Amount: 1 Mark
Estimated Amount: 1 Mark
We need to estimate 1398 - 526.
1398 > 526.
∴ we will round off these numbers to the nearest hundreds.
1398 can be rounded off to 1400.
526 can be rounded off to 500.
Estimated difference:
1400 - 500 = 900
The actual amount left with him= 1398 - 526 = 872
The difference between the estimated amount left to him, and the actual amount left with him=900 - 872 = 28.
