Choose one number which is similar to the numbers in the given set:

Given that: 471, 489, 759

633

The correct answer is Option (4) → 633

The logic here is :

abc ⇒ a + b + c = cd ⇒ c + d = 3

i) 471 ⇒ 4 + 7 + 1 = 12 ⇒ 1 + 2 = 3

ii) 489 ⇒ 4 + 8 + 9 = 21 ⇒ 2 + 1 = 3

i) 759 ⇒ 7 + 5 + 9 = 21 ⇒ 2 + 1 = 3

Similarly, after checking all options, we get the answer from option (iv)

iv) 633 ⇒ 6 + 3 + 3 = 12 ⇒ 1 + 2 = 3
