Question:
If 5 A + B 3 = 65, then the value of A and B is
(a) A = 2, B = 3
(b) A = 3, B = 2
(c) A = 2, B = 1
(d) A = 1, B = 2
Solution:
The correct answer is option (c) A = 2, B = 1
Explanation:
In the 1’s column A +3 = 5
When A is added with 3, it gives 5
Since A is a digit, it should be between 0 and 9
When you substitute A = 2, you will get 2+3 = 5
Similarly, repeat the process for 10’s column
Then we will get B= 1
Therefore A= 2, and B = 1
