A whole number is added to 25 and the same number is subtracted from 2

1.	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» (C) 50 Let us assume the number be x. From the question it is given that, number is added to 25 = x + 25 The same number is subtracted to from 25 = 25 – x Then, the sum of the resulting numbers is = (x + 25) + (25 – x) = x + 25 + 25 – x = 50 + x – x = 50 + 0 = 50

Answer»

(C) 50

Let us assume the number be x.

From the question it is given that, number is added to 25 = x + 25

The same number is subtracted to from 25 = 25 – x

Then, the sum of the resulting numbers is = (x + 25) + (25 – x)

= x + 25 + 25 – x

= 50 + x – x

= 50 + 0

= 50
