Correct Answer: (3, 5)
Solution : Given: 8 × 20 ÷ 3 + 9 – 5 = 38
Let's check the options – First option: (8, 9) Solving L.H.S. of the equation – = 9 × 20 ÷ 3 + 8 – 5 = 60 + 3 = 63 ≠ 38 Second option: (3, 5) Solving L.H.S. of the equation – = 8 × 20 ÷ 5 + 9 – 3 = 32 + 9 – 3 = 38 = R.H.S. Third option: (3, 9) Solving L.H.S. of the equation – = 8 × 20 ÷ 9 + 3 – 5 = 17.78 – 2 = 15.78 ≠ 38 Fourth option: (3, 8) Solving L.H.S. of the equation – = 3 × 20 ÷ 8 + 9 – 5 = 7.5 + 4 = 11.5 ≠ 38
So, only the second option satisfies the given condition. Hence, the second option is correct.
