The number which exceeds 20% of itself by 40.the number is

Answer 1

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  

Hope this helps!

Answer 2

(20/100)x+40=x(let x be the number and 20% means 20/100)

x=(1/5)x+40

x-(1/5)x=40

4x/5=40

4x=200

x=50
