Correct Answer: 3 and 9
Solution : Given: 7 – 3 ÷ 9 × 2 + 4
Interchange the numbers according to the options. Let's check the options – First option: 2 and 9 = 7 – 3 ÷ 2 × 9 + 4 = 7 – 1.5 × 9 + 4 = –2.5 ≠ 5 Second option: 7 and 4 = 4 – 3 ÷ 9 × 2 + 7 = 4 – 0.666 +7 = 10.334 ≠ 5 Third Option: 3 and 9 = 7 – 9 ÷ 3 × 2 + 4 = 7 – 6 + 4 = 5 Fourth Option: 4 and 2 = 7 – 3 ÷ 9 × 4 + 2 = 7 – 1.333 + 2 = 7.667 ≠ 5
So, only the third option satisfies the equation. Hence, the third option is correct.
