ABC
ABC
+ABC
_____
CCC
_____
FIND A,B,C WHERE A,B and C are not equal

Answer 1

Answer: 3*(abc) = ccc

300a+30b+3c = 100c+10c+c

300a+30b = 108c

100a + 10b = 36c

Looking at RHS, we can see that C would be greater than 3 to make LHS postive

So for C=4 and a=1

100+10b = 144

b = 4.4

So for C=5 and a=1

100+10b = 180

b = 8

so a = 1, b= 8 and c=5

abc- ab - ac - a - b - c = 40 - 8 - 5 - 1 - 8 - 5 = 13

Answer 2

Hey!

C=5

B=8

A=1

185+185+185 = 555

Hope it help
