Question
Find the value of the letters in the following question.
C B A
+ C B A
1 A 3 0
Solution
C B A
We have, + C B A
1 A 3 0
In first column, A + A = 0
⇒ A = 0 or 5
For A = 0, the second and third column, sums are not satisfied.
So, A = 5
Now, in second column,
B + B + 1 = 3
For B = 1, third column sum is not satisfied.
So, B = 6
Again, in third column, C + C + 1 = 1A
⇒ C + C = 15 – 1
⇒ 2C = 14
⇒ C = 7
Hence, A = 5, B = 6 and C = 7
