Question

C and D each represent different digits. For example, if C =2,then CCC = 222. If C + CC = D4, What number should be in the place of C​

Answer 1

2

Explanation:

Let's solve the equation step by step:

Given: C + CC = D4

To find the value of C, we need to find a value that satisfies the equation.

Since C represents a single digit, we know that C must be between 0 and 9.

Let's substitute some values for C and see if any of them satisfy the equation:

For C = 0:

0 + 00 = D4

0 + 0 = D4

0 = D4

This equation is not possible because there is no digit D that, when added to 0, gives a result of 4.

For C = 1:

1 + 11 = D4

1 + 1 = D4

2 = D4

This equation is not possible because there is no digit D that, when added to 1, gives a result of 4.

For C = 2:

2 + 22 = D4

2 + 2 = D4

4 = D4

In this case, C = 2 satisfies the equation.

Therefore, the number in the place of C is 2.
