Answer & explanation
Correct answer: option 1
(4, 67, 20)
The logic followed here is:
Given
43 + 4 = 64 + 3 = 67 ⇒ Ist number3 + Ist number
4 × (4 + 1 ) = 4 × 5 = 20 ⇒ Ist number × (Ist number + 1 ) = IIIrd number
Similarly (3, 30, 12)
33 + 3 = 27 + 3 = 30 ⇒ Ist number3 + Ist number
3 × (3 + 1 ) = 3 × 4 = 12 ⇒ Ist number × (Ist number + 1 ) = IIIrd number
