বিস্তারিত ব্যাখ্যা ও বিশ্লেষণ:
Solution:
Let the beginning price of January = 100x
The price of a stock increased by 20% in January.
Price of stock become = 100x + 100x of 20%
= 100x + (100x × 20)/100
= 120x
And then the stock price decreased by 10% in February
Price of stock become = 120x - 120x of 10%
= 120x - (120x × 10)/100
= 108x
ATQ,
108x = 108
⇒ x = 108/108
∴ x = 1
Therefore the price at the beginning of January
= 100 × 1
= Tk. 100
The price at the beginning of January was Tk. 100.
