Correct Answer: ÷, ×, =, +


Solution : Let's check the options –
First option: ÷, –, =, ×
Equation after replacing the signs ⇒ 16 ÷ 4 – 5 = 14 × 6
4 – 5 = 14 × 6
= –1 ≠ 84 (L.H.S. ≠ R.H.S.)
Second option: –, ×, +, =
Equation after replacing the signs ⇒ 16 – 4 × 5 + 14 = 6
Solving the L.H.S. of the equation –
⇒ 16 – 4 × 5 + 14
= 16 – 20 + 14
= 30 – 20
= 10 (L.H.S. ≠ R.H.S.)
Third option: ÷, ×, =, +
Equation after replacing the signs ⇒ 16 ÷ 4 × 5 = 14 + 6
4 × 5 = 20
= 20 (L.H.S. = R.H.S.)
Fourth option: ÷, +, =, –
Equation after replacing the signs ⇒ 16 ÷ 4 + 5 = 14 – 6
16 ÷ 4 + 5 = 8
= 4 + 5 = 8
= 9 ≠ 8 (L.H.S. ≠ R.H.S.)

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