Correct Answer: 3 and 6

Solution : Given:
4 × 6 – 3 + 8 = 14

Replace the given numbers in the options one by one with the original numbers in the given equation.
Let's check each option –
First option: 3 and 6
4 × 6 – 3 + 8 = 14
⇒ 4 × 3 – 6 + 8 = 14
⇒ 12 – 6 + 8 = 14
⇒ 14 = 14
Second option: 6 and 4
4 × 6 – 3 + 8 = 14
⇒ 6 × 4 – 3 + 8 = 14
⇒ 24 – 3 + 8 = 14
⇒ 29 ≠ 14
Third option: 3 and 8
4 × 6 – 3 + 8 = 14
⇒ 4 × 6 – 8 + 3 = 14
⇒ 24 – 8 + 3 = 14
⇒ 19 ≠ 14
Fourth option: 8 and 14
4 × 6 – 3 + 8 = 14
⇒ 4 × 6 – 3 + 14 = 8
⇒ 24 – 3 + 14 = 8
⇒ 35 ≠ 8

So, only the first option satisfies the equation. Hence, the first option is correct.
