Choose one number which is similar to the numbers in the given set:
Given that: 471, 489, 759
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 633
Every number of the given set is divisible by 3: the sum of its digits is a multiple of 3.
471: \(4+7+1=12\)
489: \(4+8+9=21\)
759: \(7+5+9=21\)
Testing the options in the same way:
Option (1) 581 — \(5+8+1=14\), not a multiple of 3
Option (2) 479 — \(4+7+9=20\), not a multiple of 3
Option (3) 382 — \(3+8+2=13\), not a multiple of 3
Option (4) 633 — \(6+3+3=12\), a multiple of 3, so 633 \(=3\times211\) belongs to the set
