Question

a number exceeds 20% of itself by 40
​

Answer 1

Answer: 50

Step-by-step explanation:

If x is the number, then by question,

x - (20% of x) = 40

or, x - x/5 = 40

or, 4x/5 = 40

So, x = 50.

Thus, the number is 50.

Answer 2

Answer:let the number be x.  

So, 20% of x

         = (20/100) *x

         =x/5  

Given,  

x - x/5 = 40  

4x/5 = 40  

x = 40*5/4

 

  = 50
