You must be familiar with the computation of 40% of 50, in order to figure out if your results are good or bad. Regarding our earlier speculation, you only tended to get 20 marks out of 50 which sounds quite worrying. However, the condition can be of countless kinds and such topics can be beneficial in your daily practices.

The same answer can be achieved by taking the fraction 40/100 and multiplying it by 50. The final solution will come out to be 20 when you solve the equation.

Some consumer laws require retailers and other merchants that the item was sold at the original price for some minimum amount of time, for example 2-4 weeks, before a discount can be announced on it. For example, in the UK there was a 28-day price establishment recommendation, but it was recently dropped . In other countries there are no such laws and regulations meaning that an item advertised as being sold at a given percentage off, might not actually be any cheaper than usual. Again, staying vigilant and minding the local regulatory framework will make sure the percent off you calculate represents an actual discount rather than an imaginary advertising trick.Let’s say there is a flat screen TV you want to buy, and it is on sale with a discount of 25% off the original price of $2,000, due to a promotion or a coupon that you have. Plugging the numbers into the above formula we can calculate how much is 25% off $2000. Doing so, we get:

The savings of such a price reduction are then $2000 – $1500 = $500, so with a discount of 25% you save $500 on a $2,000 TV. Here is a brief table showing how much you would save on that same TV with different levels of discounts.
