(605, 110, 11)

(660, 40, 33)

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. (720, 120, 12).

Logic: (2nd number × 3rd number) ÷ 2 = 1st number

(605, 110, 11) ⇒ (110 × 11) ÷ 2 = 1210 ÷ 2 = 605

(660, 40, 33) ⇒ (40 × 33) ÷ 2 = 1320 ÷ 2 = 660

(720, 120, 12) ⇒ (120 × 12) ÷ 2 = 1440 ÷ 2 = 720
