if the shirt is priced at Rs P and is on a discount of 20%, but if the shopkeeper buys that shirt, he will he granted an additional 10% discount, what will be the price of the shirt when the shopkeeper buy it?
Explanation
- Calculate the price after the first discount of 20%:
Price after first discount=P×(1−0.20)=P×0.80
- Calculate the additional 10% discount on the already discounted price:
Price after additional discount=Price after first discount×(1−0.10)=(P×0.80)×0.90
- Simplify the calculation:
Final price=P×0.80×0.90=P×0.72
