Correct Answer: ÷ and +

Solution : Given:
4 ÷ 32 + 8 × 9 – 5 = 35

After interchanging signs according to the given options.
First option: × and –
Solving the L.H.S. of the equation –
4 ÷ 32 + 8 – 9 × 5 = 35
0.125 + 8 – 45
–36.875 ≠ 35
Second option: ÷ and +
Solving the L.H.S. of the equation –
4 + 32 ÷ 8 × 9 – 5 = 35
4 + 4 × 9 – 5
40 – 5
35 = 35 (L.H.S. = R.H.S.)
Third option: ÷ and ×
Solving the L.H.S. of the equation
4 × 32 + 8 ÷ 9 – 5 = 35
4 × 32 + 0.88 – 5
123.88 ≠ 35
Fourth option: × and +
Solving the L.H.S. of the equation –
4 ÷ 32 × 8 + 9 – 5 = 35
0.125 × 8 + 9 – 5
5 ≠ 35

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