Replace A, B, C by suitable numerals

Answer»

We know that in the unit place A + A + A = A

3A = A, which is not possible

Since A is greater than 10, where, 1 is carried over to tens place

A + A + A = A + 10

3A = A + 10

3A-A = 10

2A=10

∴A=10/2 = 5

Now in tens place

∴B = 1 where 1 is carried over
