By interchanging which two signs will the given equation be correct?
$$11 \div 77 + 253 \times 23 - 800 = 58$$

Option (a) - and $$\div$$

$$11 - 77 + 253 \times 23 \div 800 = 58$$

The above given equation is not satisfied. Because it will give values in decimals.

Option (b) $$\times$$ and $$\div$$

$$11 \times 77 + 253 \div 23 - 800 = 58$$

$$ 847 + 11 - 800 = 58$$

$$ 858 - 800 = 58$$

58 = 58

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

Option (c) + and -

$$11 \div 77 - 253 \times 23 + 800 = 58$$

The above given equation is not satisfied. Because it will give values in fractions.

Option (d) - and $$\times$$

$$11 \div 77 + 253 - 23 \times 800 = 58$$

The above given equation is not satisfied. Because it will give values in fractions.
