Estimation in Percentages
Your bill in a shop is Rs. 498. 20 and the shopkeeper gives a discount of 10%. How would you estimate the amount to be paid?
(i) Round off the bill to the nearest tens of Rs. 498.20 i.e. to 500
(ii) Find 10% of this i.e., Rs
Therefore reduce your bill amount by Rs. 50 which will be Rs. 450 approximately.
