Question

In the following correctly worked addition sum, A,B,C and D represent different digits, and all the digits in the sum are different. What is the sum of A,B,C and D? A. 23 B. 22 C. 18 D. 16 E. 14"

Answer 1

The sum of A, B, C, and D is 4.

Step-by-step explanation:

The sum of A, B, C, and D can be obtained by looking at the addition sum provided. Since all the digits in the sum are different, we can assume that each digit represents a different value. From the provided options, we need to find the correct sum. Let's analyze the sum:

A + B = B + A

From this equation, we can conclude that A and B are the same digit. So, let's assume A = 2 and B = 2. Now, let's substitute these values into the equation:

2 + 2 = 2 + 2

Simplifying, we get 4 = 4, which is a true statement. Therefore, the sum of A, B, C, and D is 4.
