Correct Answer: 284


Solution : Given:
214 – 65 × 5 ÷ 7 + 21 = ?

After interchanging + with –, and × with ÷, the equation will be as follows –
= 214 + 65 ÷ 5 × 7 – 21
= 214 + 13 × 7 – 21
= 214 + 91 – 21
= 305 – 21
= 284

So, 284 is the required answer to the given equation. Hence, the fourth option is correct.
