A natural number is added to 250 and the same number is subtracted from 250. The sum of the two resulting numbers so obtained is

Correct option is C

Given
A natural number is added to 250.
The same natural number is subtracted from 250.

Formula Used
Sum = (a + x) + (a - x) = 2a

Solution
Let the natural number be x.

First resulting number = 250 + x

Second resulting number = 250 - x

Sum of the two resulting numbers = (250 + x) + (250 - x)

Sum = 250 + x + 250 - x

Sum = 500

So the correct answer is (c)
