A book is originally priced at BDT 900, but marked down by 30%. Again when the actual sales occurs a discount of 10% is offered on the marked price, what is the final sales price in BDT?

Correct Answer: 360
At 30% discount, marked down price = 70% of 900 = 630 BDT. Another 10% discount on marked price = 10% of 900 = 90 BDT Final sale = 630 - 90 = 540 BDT.
