I mean what is the discount per cent

anonymous · Answer

ahh.. that makes sense ;)

$$\LARGE 240(1-x\%)=192$$

$$\LARGE 240(1-\frac{x}{100 })=192$$
$$\LARGE 240-\frac{240x}{100 }=192$$
$$\LARGE 240-\frac{24x}{10 }=192$$
multiply both sides by 10 
$$\LARGE 2400-24x=1920$$
$$\LARGE -24x=-480  $$

can you solve it from here? :)

why wtf??   what's there to get suprised of ? o.O

anonymous · Answer

Original price: $240
Sale price: $192

$$240-192=48$$

You saved $48 on the product (your discount). Find the percentage of $48 compared to the original price, $240.

$$\frac{48}{240}*100=20$$

So you received a 20% discount.
