-
- Let the number be 'x'
Let 'y' equal to the number which 'x' exceeds 25% of itself
that is 'y'=125% of 'x' and it is equal to x+40
so x+40=125% of x.
therefore the number 'x'=160 is the answer - 12 years agoHelpfull: Yes(5) No(3)
- 160/3
If no is x, then
x exceeds 25% of x by 40.
as per condition
x= 0.25x +40
0.75x =40
x= 40/0.75 = 40*100/75 = 160/3 - 12 years agoHelpfull: Yes(5) No(2)
- 160/3
x= x/4 +40
3x/4 =40
x=160/3 - 12 years agoHelpfull: Yes(3) No(0)
- x= x/4 +40
3x/4 =40
x=160/3 - 10 years agoHelpfull: Yes(0) No(0)
- to solve this equation do the following:
start with:
x = .2x + 40
subtract .2x from both sides of this equation to get:
.8x = 40
divide both sides of that equation by .8 to get:
x = 40/.8
simplify to get:
x = 50
x is your number.
check the number out by applying the logic of the original statement to it.
20% of 50 is equal to 10.
50 exceeds 10 by 40.
your answer is good.
