Question:
Find A and B in the addition. A +A +A =B A
U take B= 5
Why not 4?
4+4+4 = 12
Answer:
Given, A + A + A = BA
It means the value of left side of A is same as the value of right side of A.
B may has any value.
So, If A = 5, then
5 + 5 + 5 = 15
If A = 4, then
4 + 4 + 4 = 12
Now, 4 ≠ 2
So, A = 5 satisfies the addition A + A + A = BA
