Correct Answer: × and +

Solution : Given:
13 + 145 ÷ 29 × 52 – 11 = 106

Let's check the options –
First option: – and ×
13 + 145 ÷ 29 – 52 × 11 = 106
On solving the L.H.S. of the given equation –
= 13 + 145 ÷ 29 – 52 × 11
= 13 + 5 – 52 × 11
= 13 + 5 – 572
= –554 ≠ 106
Second option: × and +
13 × 145 ÷ 29 + 52 – 11 = 106
On solving the L.H.S. of the given equation –
= 13 × 145 ÷ 29 + 52 – 11
= 13 × 5 + 52 – 11
= 65 + 52 – 11
= 106
Third option: ÷ and –
13 + 145 – 29 × 52 ÷ 11 = 106
On solving the L.H.S. of the given equation –
= 13 + 145 – 29 × 52 ÷ 11
= 13 + 145 – 29 × 4.73
= 13 + 145 – 137.17
= 20.83 ≠ 106
Fourth option: ÷ and +
13 ÷ 145 + 29 × 52 – 11 = 106
On solving the L.H.S. of the given equation –
= 13 ÷ 145 + 29 × 52 – 11
= 0.09 + 29 × 52 – 11
= 0.09 + 1508 – 11
= 1497.09 ≠ 106

So, only the second option satisfies the given equation. Hence, the second option is correct.
