Directions: In the following questions, from the given four alternatives, select the number which is most similar to the given set.

Given set: 363, 489, 579

Logic: Digit Sum of Each Number = 3

For, 363:

3 + 6 + 3

= 12

= 1 + 2

= 3

For, 489:

4 + 8 + 9

= 21

= 1 + 2

= 3

For, 579:

5 + 7 + 9

= 21

= 1 +2

= 3

Now checking each options one by one;

Option 1:

562 →

5 + 6 + 2

= 13

= 1 + 3

= 4 ≠ 3

Digit sum is 4.

Option 2:

382 →

3 + 8 + 2

= 13

= 4 ≠ 3

Digit sum is 4

Option 3:

471 → 

4 + 7 + 1

= 12

= 3

Digits sum is 3.

Option 4:

281 → 

2 + 8 + 1

= 11

= 1 + 1

= 2 ≠ 3

Hence, the correct answer is "471".
