Mr. Dragmire2016-10-20http://www.thejournal.ie/profile/201271/here-i-without-trial-error-5559142/Here is how I got 3636 without trial and error. Started the same as everyone else: 6ABC = 6CBA so A=C 6ABA = 1.75(ABA6) 6000+100A+10B+A = 1750A+175B+17.5A+10.5 Tidying up we get 5989.5 = 1666.5A+165B Divide by 16.5 to get 363 = 101A + 10B And 101A + 10B is ABA. (100A+10B+A) So A is 3 and B is 6. You can also work it out by changing 1.75 into 7/4 and cross multiplying. You’ll get the line 24000+400A+40B+4A = 7000A+700B+70A+42 From this we can see that only the 4A can make the 2 in 42. No other term can affect the units place. A must then be 3 as it is the only whole number you can multiply by 4 and get a number ending in 2 which is 12. You can then sub in A = 3 to find B.
