বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Price of 6 mangoes = Price of 9 oranges
⇒ (Price of 1 mango) : (Price of 1 orange) = 9/6 = 3 : 2
Suppose, the price of each mango is Tk. 3x, and the price of each orange is Tk. 2x.
According to the question,
50×3x + 30×2x = 420
⇒ x = 2
Price of each mango = 3×2 = Tk. 6.
