If Sharon is 3 years younger, then it's s = 3-b. However, it's twice her brothers age, which makes the formula our final answer, A, or 
How about raising 286 up by 14 to 300 and compensating by lowering 428 by the same 14 Since I know that 14 + 14 is 28 then 28-14 is 14
So 428 - 14 = 414
So now I have 414 + 300 which I can do mentally - the answer is 714 and is also the answer to the original problem 428 + 286
Compensation works very well - bring one number up or down to a rounded number and compensate by doing the opposite to the other - instead of 199 + 457 - try 200 + 456
Same answer and because one of the numbers is nicely rounded, it is easy to add the other.
One more: 207 + 182 becomes 200 + 189 =389 I lowered one by 7 and raised the other one by the same 7.

{41, 10, 41, 41, 29}
The outlier has to be very different from over numbers,
so it is 10.
If you need only one.
the 7 digit is in the ten thousands place
the 0 is in the thousands place
the 6 is in the hundreds place
the 8 is in the tens place
the 1 is in the units place
