A whole number is added to 25 and the same number is subtracted from 25. The sum of the resulting numbers is
A. 0

B. 25

C. 50

D. 75

Answer :

Let the whole number = a


First number = 25 + a


Second number = 25 - a


Sum of resulting numbers = 25 + a + (25 - a)


= 25 + a + 25 - a


= 25 + 25 + a - a


= 50 + 0


= 50
