Correct Answer: 70

Solution : Given: 
× stands for +, + stands for ÷, – stands for × and ÷ stands for –
76 ÷ 5 – 6 + 3 × 4 = ?

After interchanging the given mathematical signs, the equation becomes –
76 – 5 × 6 ÷ 3 + 4
76 – 5 × 2 + 4
76 – 10 + 4
= 70

So, 70 is the answer to the given equation. Hence, the second option is correct.
