Question

if 25% of a number is added to 45 then the result will be the number itself then what is the number ​

Answer 1

Answer:

Step-by-step explanation:

If 25% of a number is added to 45 then the result will be the number itself.

Let the number be 'x'.

(25% of x) + 45 = x

=>  25x/100 + 45 = x

=> x/4 + 45 = x

=>(x+180)/4 = x

cross multiply,

x+180 = 4x

=> 3x = 180 => x=60

Answer 2

Answer:

60

Step-by-step explanation:

Let the number =$x$

Therefore,

$\frac{25}{100}x+45=x\\Therefore,\\\frac{1}{4} x +45=x\\Therfore,\\45=x-\frac{1}{4}x=\frac{3}{4}x\\Therfore,\\ \frac{3}{4}x=45\\Therefore,\\3x=45*4=180\\Therefore,\\x=\frac{180}{3} =60-ANS$

The number is 60
