Correct Answer: + and –

Solution : Given:
17 × 4 + 6 ÷ 2 – 27 = 92

Replace the given symbols in the options one by one with the original symbols in the given equation.
First option: + and ×
= 17 + 4 × 6 ÷ 2 – 27
= 17 + 4 × 3 – 27
= 17 + 12 – 27
= 29 – 27
= 2 ≠ 92
Second option: ÷ and ×
= 17 ÷ 4 + 6 × 2 – 27
= 4.25 + 6 × 2 – 27
= 4.25 + 12 – 27
= 16.25 – 27
= –10.75 ≠ 92
Third option: + and –
= 17 × 4 – 6 ÷ 2 + 27
= 17 × 4 – 3 + 27
= 68 – 3 + 27
= 95 – 3
= 92
Fourth option: × and –
= 17 – 4 + 6 ÷ 2 × 27
= 17 – 4 + 3 × 27
= 17 – 4 + 81
= 98 – 4
= 94 ≠ 92

Here, only the third option satisfies the R.H.S. of the given equation. Hence, the third option is correct.
