Correct Answer: 20 ÷ 4 – 5 × 6 + 3 = 32

Solution : Given:
+ and –

Replace the given symbols in the options one by one with the original symbols in the given equation.
First option: 7 – 5 × 3 + 24 ÷ 6 = 7
⇒ 7 + 5 × 3 – 24 ÷ 6 = 7
= 7 + 15 – 4
= 18 ≠ 7
Second option: 20 ÷ 4 – 5 × 6 + 3 = 32
⇒ 20 ÷ 4 + 5 × 6 – 3 = 32
= 5 + 30 – 3
= 32
Third option: 4 + 5 × 2 – 9 ÷ 3 = 5
⇒ 4 – 5 × 2 + 9 ÷ 3 = 5
= 4 – 10 + 3
= –3 ≠​​​​​​​ 5
Fourth option: 7 × 3 – 10 + 8 ÷ 2 = 29
​​​​​​​⇒ 7 × 3 + 10 – 8 ÷ 2 = 29
= 21 + 10 – 4
= 27 ≠ 29

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