Answer»

The GIVEN equation is : 516 × 30 ÷ 10 + 4 = 49

Let’s check each option,

1) – and + → 5 + 16 × 30 ÷ 10 – 4 = 49 = 49

2) ÷ and × → 5 – 16 ÷ 30 × 10 + 4 = 3.66 ≠ 49

3) × and – → 5 × 16 – 30 ÷ 10 + 4 = 81 ≠ 49

4) ÷ and – → 5 ÷ 16 × 30 – 10 + 4 = 3.375 ≠ 49

Hence, by interchanging – and + the equation will be CORRECT.
