Which two signs should be interchanged to make the given equation correct?
$$(560\div80)+90\times8-38=600$$
By Trial and Error method,
Option A
$$(560\div80)-90\times8+38=600$$
$$7-90\times8+38=600$$
$$7-720+38=600$$
$$-675=600$$
Hence Option A is incorrect
Option B
$$(560+80)\div90\times8-38=600$$
$$640\div90\times8-38=600$$
$$\frac{64}{9}\times8-38=600$$
The value will be decimal after solving which is not possible
Option C
$$(560-80)+90\times8\div38=600$$
$$480+90\times8\div38=600$$
$$480+720\div38=600$$
$$480+\frac{360}{19}=600$$
The value will be decimal after solving which is not possible
Option D
$$(560\div80)\times90+8-38=600$$
$$7\times90+8-38=600$$
$$630+8-38=600$$
$$600=600$$
Hence, the correct answer is Option D
