Correct answer: (D) 24.1
Term by term: 4.5 × 4 = 18; 1.5 of 2 = 3, so 12 ÷ 3 = 4; 0.6 of 7.5 = 4.5. Now 18 + 4 − 2.4 + 4.5 = 24.1. ('of' binds before ÷; doing 12 ÷ 1.5 first is the trap.)

सही उत्तर: (D) 24.1
पद-दर-पद: 4.5 × 4 = 18; 1.5 का 2 = 3, अतः 12 ÷ 3 = 4; 0.6 का 7.5 = 4.5। अब 18 + 4 − 2.4 + 4.5 = 24.1। ('का' ÷ से पहले होता है; पहले 12 ÷ 1.5 करना गलती है।)
