Question

if 50% of a number is added to 50 the result is the number itself find the number

Answer 1

----------------------------------------

Here is the solution:

----------------------------------------

Let the number be x

Form equation and solve for x:

50 + 0.5x = x

Subtract 0.5x from both sides:

0.5x = 50

Divide both sides by 0.5:

x = 100

Answer: The number is 100.

Answer 2

Greetings..!

Let the required number be x .

SO, 50 percent of x = (50/100)*x = x/2

According to problem , we need to add this to 50,and form equation :

⇒50 + (x/2) = x

⇒ 100+x = x      { taking L.C.M of 1 and 2 as 2 }

⇒100 = x-x

⇒100=x

Answer : Hence, the number is 100.
