1. A discount electronics store normally sells all merchandise at a discount of 10 percent to 30 percent off the marked retail price. If during a special sale an additional 20 percent were to be deducted from the discount price; what would be the lowest possible price of an item marked retail price is Tk. 260?

  • A. Tk. 145.60
  • B. Tk. 145.60
  • C. Tk. 145.60
  • D. Tk. 145.60

Answer: Option A

Explanation:

এই Math টিতে 'discount' এর উপর 'discount' হিসাব করতে হবে। যদি 30% off থাকে , তবে (100 - 30)  =  70% price এ বিক্রি হচ্ছে।
so 30% discount এর জন্য 260Tk হবে  =  260  ×  .70
                                         =  182 Tk.
আবার, এই discount price এর উপর 20% discount  =  182  ×  .80
                                                       =  145.60 টাকা
