Description
Imagine: there's a sale at M.Video, a Samsung TV for 35,000 rubles, 25% off. By the time you get out your calculator, the deal is gone. Want to instantly calculate the savings and save seconds?
Here's a simple trick: to find 10% off the price, simply move the decimal point one place to the left. For 35,000 rubles, that's 3,500. For a 20% discount, multiply that amount by two – you'll get a 7,000 ruble savings.
What about compound interest, for example, 15% on a €1,200 item? First, find 10%—that's €120. Then find half of 10% (or 5%)—that's €60. Add it all up: €120 plus €60—that's a total savings of €180.
This method is universal. If Nike sneakers cost 8,000 rubles with a 30% discount, 10% is 800 rubles. Multiply by three – your savings are 2,400 rubles. This way, you can save thousands over the course of a year, just like on the legendary Black Friday.
Now, whether it's a stylish Zara coat for 5,000 rubles with a 40% discount or a De'Longhi coffee machine, you'll be able to see the deal faster than any salesperson. Practice, and discounts will be yours in a split second!
