Correct Answer: 154


Solution : Given:
+ means –, – means ×, × means ÷, ÷ means +
137 ÷ 56 × 7 – 6 + 31 = ?

After interchanging the given mathematical signs, we get –
137 + 56 ÷ 7 × 6 – 31
137 + 8 × 6 – 31
137 + 48 – 31
= 154

So, 154 is the answer to the given equation. Hence, the fourth option is correct.
