Correct Answer: ÷ and +

Solution : Given:
110 ÷ 20 + 5 × 13 – 9

Replace the given symbols in the options one by one with the original symbols in the given equation.
First option: + and ×
= 110 ÷ 20 × 5 + 13 – 9
= 5.5 × 5 + 13 – 9
= 27.5 + 4
= 31.5 ≠ 153
Second option: ÷ and +
= 110 + 20 ÷ 5 × 13 – 9
= 110 + 4 × 13 – 9
= 110 + 52 – 9
= 153
Third option: – and ×
= 110 ÷ 20 + 5 – 13 × 9
= 5.5 + 5 – 117
= –106.5 ≠ 153
Fourth option: + and –
= 110 ÷ 20 – 5 × 13 + 9
= 5.5 – 65 + 9
= 14.5 – 65
= –50.5 ≠ 153

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