Which two signs need to be interchanged to make the given equation correct?
$$104 \div 8 + 6 - 9 \times 3 = 34$$

Option (a) $$+, -$$

$$104 \div 8 - 6 + 9 \times 3 = 34$$

$$13 - 6 + 27 = 34$$

7+ 27 = 34

34 = 34

The given equation is satisfied. So this is the correct answer.

Option (b) $$\div, +$$

$$104 + 8 \div 6 - 9 \times 3 = 34$$

The given equation is not satisfied. Because it will give the values in fraction which is not possible. So this is not the correct answer.

Option (c) $$-, \times$$

$$104 \div 8 + 6 \times 9 - 3 = 34$$

$$13 + 54 - 3 = 34$$

$$64\ne\ 34$$

The given equation is not satisfied. So this is not the correct answer.

Option (d) $$+, \times$$

$$104 \div 8 \times 6 - 9 + 3 = 34$$

$$13 \times 6 - 9 + 3 = 34$$

$$78 - 9 + 3 = 34$$

$$72\ne\ 34$$

The given equation is not satisfied. So this is not the correct answer.
