Let the six-digit number be ABCDEF
F = A+B+C, E= A+B, C=A, B= 2A, D= E+F
D=2A+2B+C=6A+C, we have to find the largest possible value of D
The only possible value of A is 1 because if A = 2, D = 12+C even
if C is 0 D is two digit number If A= 1, then C = 1
D = 6*1+1=7
F = A+B+C, E= A+B, C=A, B= 2A, D= E+F
D=2A+2B+C=6A+C, we have to find the largest possible value of D
The only possible value of A is 1 because if A = 2, D = 12+C even
if C is 0 D is two digit number If A= 1, then C = 1
D = 6*1+1=7

Given information:
In a six-digit number:
- The sixth digit is the sum of the first three digits.
- The fifth digit is the sum of the first two digits.
- The third digit is equal to the first digit.
- The second digit is twice the first digit.
- The fourth digit is the sum of the fifth and sixth digits.
Objective:
To find the largest possible value of the fourth digit.
Method:
We can solve this problem by considering the given conditions and evaluating the possibilities step by step.
Step 1: The third digit is equal to the first digit.
- Let's assume the first digit is 'x'. So, the third digit is also 'x'.
Step 2: The second digit is twice the first digit.
- The second digit is '2x'.
Step 3: The fifth digit is the sum of the first two digits.
- The fifth digit is 'x + 2x = 3x'.
Step 4: The fourth digit is the sum of the fifth and sixth digits.
- The fourth digit is '3x + (x + 2x) = 6x'.
Step 5: The sixth digit is the sum of the first three digits.
- The sixth digit is 'x + x + 2x = 4x'.
Step 6: We need to find the largest possible value of the fourth digit.
- To find the largest possible value of 'x', we need to consider the largest possible value for the other digits.
Step 7: Evaluating possibilities.
- Since the sixth digit is the sum of the first three digits, it cannot be greater than 27 (9 + 9 + 9 = 27). So, the maximum value of '4x' can be 27.
- If '4x' is equal to 27, then 'x' would be 6. But in this case, the third digit (x) would be equal to the first digit (6) which violates the condition.
- The next possibility is '4x' = 24. In this case, 'x' would be 6. But again, the third digit (x) would be equal to the first digit (6) which is not possible.
- The next possibility is '4x' = 21. In this case, 'x' would be 5. But again, the third digit (x) would be equal to the first digit (5) which is not possible.
- The next possibility is '4x' = 18. In this case, 'x' would be 4. But again, the third digit (x) would be equal to the first digit (4) which is not possible.
- The next possibility is '4x' = 15. In this case, 'x' would be 4. But again, the third digit (x) would be equal to the first digit (4) which is not possible.
- The next possibility is '4x' = 12. In this case, 'x' would be 3. But again, the third digit (x) would be equal to the first digit (3) which is not possible.
- The next possibility is '4

Step 4: The fourth digit is the sum of the fifth and sixth digits.
- The fourth digit is '3x + (x + 2x) = 6x'.
Step 5: The sixth digit is the sum of the first three digits.
- The sixth digit is 'x + x + 2x = 4x'.
Step 6: We need to find the largest possible value of the fourth digit.
- To find the largest possible value of 'x', we need to consider the largest possible value for the other digits.
