Correct Answer: 16 + 5 – 10 × 4 ÷ 3 = 9
Solution : Given: × means addition, – means division, ÷ means subtraction, and + means multiplication.
Replace the mathematical signs in the equations and solve the equations one by one. Let's check the given options – First option: 16 × 5 ÷ 10 + 4 – 3 = 19 ⇒ 16 + 5 – 10 × 4 ÷ 3 = 19 Solving L.H.S. of the equation – = 16 + 5 – 10 × 1.33 = 16 + 5 – 13.33 = 21 – 13.33 = 7.67 ≠ 19 Second option: 16 + 5 ÷ 10 × 4 – 3 = 9 ⇒ 16 × 5 – 10 + 4 ÷ 3 = 9 Solving L.H.S. of the equation – = 16 × 5 – 10 + 1.33 = 80 – 10 + 1.33 = 81.33 – 10 = 71.33 ≠ 9 Third option: 16 + 5 – 10 × 4 ÷ 3 = 9 ⇒ 16 × 5 ÷ 10 + 4 – 3 = 9 Solving L.H.S. of the equation – = 16 × 0.5 + 4 – 3 = 8 + 4 – 3 = 12 – 3 = 9 = R.H.S. Fourth option: 16 – 5 × 10 ÷ 4 + 3 = 12 ⇒ 16 ÷ 5 + 10 – 4 × 3 = 12 Solving L.H.S. of the equation – = 3.2 + 10 – 4 × 3 = 3.2 + 10 – 12 = 13.2 – 12 = 1.2 ≠ 12
So, only the third option satisfies the given condition. Hence, the third option is correct.
