Check the options: Option 1: (201, 702, 303) Sum of the digits of the first number = 2 + 0 + 1 = 3 Sum of the digits of the second number = 7 + 0 + 2 = 9 Sum of the digits of the third number = 3 + 0 + 3 = 6 Hence, option 1 is not the correct answer. |
|
Option 2: (400, 660, 800) Sum of the digits of the first number = 4 + 0 + 0 = 4 Sum of the digits of the second number = 6 + 6 + 0 = 12 Sum of the digits of the third number = 8 + 0 + 0 = 8 Hence, option 2 is not the correct answer. |
|
Option 3: (200, 600, 300) Sum of the digits of the first number = 2 + 0 + 0 = 2 Sum of the digits of the second number = 6 + 0 + 0 = 6 Sum of the digits of the third number = 3 + 0 + 0 = 3 Hence, option 3 is the correct answer. |
|
Option 4: (111, 207, 222) Sum of the digits of the first number = 1 + 1 + 1 = 3 Sum of the digits of the second number = 2 + 0 + 7 = 9 Sum of the digits of the third number = 2 + 2 + 2 = 6 Hence, option 4 is not the correct answer. |
