You can now buy 5 more oranges with TK. 75 due to reduction in price by 20 percent. Calculate the current price of one dozen of oranges?
সমাধান
সঠিক উত্তর: Option C
20% of 75 tk is: 75*20/100
= 15 tk
Thus,
one can buy 5 oranges with 15 tk.
one can buy 1 orange with 15/5 tk = 3 tk
Now,
Price of 1 orange is 3 tk
Price of 12 oranges (1 dozen) is 3*12 tk = 36 tk
