Question

If a whole number is subtracted from 20 as well as added to 20, then the sum of the resultant numbers is

Answer 1

Answer:

20 is the answer

the whole number = x

from the question,

Required sum = (20+x) + (20-x) =

20+x + 20 - x = 20

Answer 2

let the number be x

(25+x) + (25-x)

25 + x + 25 - x

50 (x is cancelled)

so the sum will be 50
