Question

when is the result of a number ,when decreased by 20% is 192 find this number with the proper way

Answer 1

hi friend
here's your answer looking for

let the original number be x.

then ,

we can write ,

$x - x \times \frac{20}{100} = 192 \\ \\ x - \frac{x}{5} = 192 \\ \\ \frac{5x - x}{5} = 192 \\ \\ 4x = 960 \\ \\ x = \frac{960}{4} \\ \\ x = 240$

so, our original number is 240

hope you are satisfied with my answer

Answer 2

the result let's take as X
so when the result is decreased by 20%
so when we so it
that is 20/100*X
so we have to subtract this
X-(20x/100)=192
100x-20x/100=192
80x=19200
x=19200/80
x=240
