The price of 357 mangoes is Tk. 1517.25. Find the approximate price of 49 dozens of such mangoes?

Question: The price of 357 mangoes is Tk. 1517.25. Find the approximate price of 49 dozens of such mangoes?

Solution:
We know that 1 dozen = 12 piece
49 dozens = 49 × 12 = 588 mangoes
Let,
x is the price for 588 mangoes.
Now,
Put the same unit on the same side
Price and mangoes are directly proportional to each other, so
⇒ 357 mangoes : 588 mangoes = 1517.25 : x
∴ x = (1517.25 × 588)/ 357 = 2499
Hence, The approximate value, x = Tk. 2500
