Explanation :-
Unit digits are C + C + C = B
=> 3 C = B
B is the multiple of 3 .
and
3(A B C ) = B B B
3(100A+10B+C ) = 100B+10B+B
=> 3(100A+10B+C ) = 111B
=>100A + 10B + C = 111B/3
=] 100A+ 10B +C = 37B
=] 100A+C = 37B-10B
=] 100A+C = 27B-----(1)
LHS is more than 100
RHS should be more than 100
By trial and error method
27×1 = 27
27×2 = 64
27×3 = 81
27×4 = 108
So For B = 4 we get 27×4 = 108 which is the first number in the multiple of 27 greater than 100
So , The possible value for B = 4
Then (1) becomes
=> 100A+C = 108
Now we have to find the pairs for A and C which are equal to 108
So, we have
If A = 1 => 100(1)+C = 108
=> 100+C = 108
=> C = 108-100
=> C = 8
If A = 2 the value becomes greater than 108
So,
(A,C) = (1,8) This pair of positive integers is only applicable for 108
So the possible value of A = 1
The possible value of C = 8
So , A = 1, B = 4 ,C= 8
Answer:-
The values of A,B and C are 1,4 and 8 respectively.
