Correct Answer: = and +

Solution : Given:
2 – 8 ÷ 4 = 6 × 3 + 18

Replace the given symbols according to the options one by one with the original symbols in the given equation.
First option: × and –
⇒ 2 × 8 ÷ 4 = 6 – 3 + 18
⇒ 2 × 2 = 3 + 18
⇒ 4 ≠ 21
Second option: = and +
⇒ 2 – 8 ÷ 4 + 6 × 3 = 18
⇒ 2 – 2 + 18 = 18
⇒ 18 = 18
Third option: × and +
⇒ 2 – 8 ÷ 4 = 6 + 3 × 18
⇒ 2 – 2 = 60
⇒ 0 ≠ 60
Fourth option: + and –
⇒ 2 + 8 ÷ 4 = 6 × 3 – 18
⇒ 2 + 2 = 0
⇒ 4 ≠ 0

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