(200 - 84)/2 = 58
and
(200 + 84)/2 = 142
For futher explication, see below.
Call the lesser and greater of the two required numbers l and g respectively. the, from the problem statement, l + g = 200 and g - l = 84. Rearrange the first of these equations to give g = 200 - l and substitute this expression into the second of the equations to result in g - (200 - g) = 84, or 2g - 200 = 84, or g 284/2 or 142. l is then (200 - 142) or 58.
The numbers are: 76 and 20
62.5 and 37.5
200 and 250
Add 200 to it because 121 plus 200 = 321
You see that there is a difference of 400 between the two numbers. Therefore, just take 400 divided by 2. This equals 200 and if you add 200 to 3600, it adds up to 3800.Another way to do this is simply find the average of the two numbers. Add 3600 and 4000 which equals 7600. Now Take 7600 divided by 2. This makes the averege of the two numbers which is 3800.
The factor pairs of 200 are (200,1)(100,2)(50,4)(40,5)(25,8)(20,10) None of them have a sum or difference of 20. Factors of 200 that add to 20 are 10 and 10.
The two numbers which add to 5 and their difference is 11 are:-3 + (-8) = 5
