Question

A number is decreased bu 23% becomes 539. Find the number

Answer 1

Lets call the number x

decreased means subtraction.  If x is decreased bt 23% then the result is

x-23%(x)  =  x-(23/100)x    or x-.23x

 

 

x-.23x=539

.77x=539

x=539/.77

x=700

 

check:  700-.23(700)=539

            700-161=539

            539=539

Answer 2

let the no be x
therefore
x-23x/100=539
77x/100=539
x=700
