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?

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
