Correct Answer: TK 81.25

Explanation:

২০% ডিসকাউন্টে পণ্যের মূল্য দাড়ায় (১০০ – ২০) টাকা = ৮০ টাকা

৩০% লাভে বিক্রয়মূল্য (১০০ + ৩০) টাকা = ১৩০ টাকা

১০০ টাকার পণ্যের বিক্রয় মূল্য = ১৩০ টাকা

৫০ টাকার পণ্যের বিক্রয় মূল্য = $\frac{১৩০x৫০}{১০০}$ =৬৫ টাকা

ডিসকাউন্ট মূল্য ৮০ টাকা হলে চাহিদামূল্য = ১০০ টাকা

ডিসকাউন্ট মূল্য ৬৫ টাকা হলে চাহিদামূল্য =$\frac{১৩০x৬৫}{৮০}$= ৮১.২৫ টাকা
