Question
Read the sentence to find out whether there is any
grammatical error in it. The error, if any, will be in one part of the sentence. Mark the part with the error as your answer. If there is no error, mark ‘No error’ as your answer (Ignore the errors of punctuation, if any). This is by far the most easier (A)/ method to solve complex (B)/ equations within (D)/ a short time. (D) / No error (E)Solution
The phrase "most easier" is incorrect because "easier" is already a comparative adjective. Using "most" with it results in a double comparison. So, "most easier" should be replaced with "easiest" or just "easier", depending on context — here, it should be "easiest" as it's superlative.
Correct sentence: This is by far the easiest method to solve complex equations within a short time.
