Question

Find the value of the letters in the following question.

   C  B  A
+ C  B  A
1  A  3  0 

Answer 1

                   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
