"0" is not counted as a natural number, but it should be used as a digit.
30+30+1++30+2+...+30+9 = 10x30+1+2+3+...+9.
1, 2, ... ,6 < 7 ; 1+2+3+4+5+6=21 .
The answer to the question is clear. The aim is to adapt you to mathematical thinking.
Numbers should be something like X37Y where X and Y are any one of the digits. For max. X=Y=9 and for min X does not exist at all
due to "at most" and Y=0
The equation 10xΔ + 2 = 12xΔ may be solved for Δ. Trial and error works also.

"Fine job, Jack!" The minister said, vigorously shaking his hand. "You are indeed a fine salesman and the church is indebted to you."
Turning to Paul, "And Paul, how many Bibles did you sell for the Church last week?"
Paul, smiling and sticking out his chest, confidently replied, "I am a professional salesman. I sold 28 Bibles on behalf of the church, and
here's $280 I collected."
The minister responded, "That's absolutely splendid, Paul. You are truly a professional salesman and the church is
indebted to you."
Apprehensively, the minister turned to Louie and said, "And Louie, did you manage to sell any bibles last week?"
Louie silently offered the minister a large envelope.
The minister opened it and counted the contents. "What is this?" The minister exclaimed. "Louie, there's $3,200.00
in here! Are you suggesting that you sold 320 Bibles for the church, door to door, in just one week?" (continues)

Louie just nodded.
"That's impossible!" both Jack and Paul said in unison. "We are professional salesmen, yet you claim to have sold 10 times as many Bibles as we
could."
"Yes, this does seem unlikely," the minister agreed. "I think you'd better explain how you managed to accomplish this, Louie..."
Louie shrugged. " III rerereal ly dododon't knknknow ffffor shshshsure," he stammered.
Impatiently, Peter interrupted. "For crying out loud, Louie, just tell us what you said to them when they
answered the door!"

A+B = 87 and AB = 37 should be solved.
Trial and error should be preferred. If A=61 then B must be 26 according to the first, sum, equation. 6126=35.
Difference must be greater.
If A is 63 B is 24 and the difference is 39.
The digits of the 2digit number can not be the same, otherwise no diff. at all.
85/17 = 5 . That means A is supposed to be a natural number greater than 5.
Originally ABC happens to be CBA after interchanging.
ABC = 100xA + 10xB + C
CBA = 100xC + 10xB + A
Difference = 100x(AC) + C  A = 99 x (A  C) i.e. a multiple of 99.
It should also be a multiple of 9 .
For the difference to be a natural number (positive) is the necessary condition A>C
Since the middle digit is the same for both, the middle digit of the diff. sholud be 9.
