Correct Answer: 108


Solution : Given:
16 ÷ 4 + 15 × 5 – 47 = ?

After interchanging + with –, and × with ÷, the equation will be as follows –
= 16 × 4 – 15 ÷ 5 + 47
= 16 × 4 – 3 + 47
= 64 – 3 + 47
= 111 – 3
= 108

So, 108 is the required answer to the given equation. Hence, the fourth option is correct.
