Q:

Read each sentence to find out whether there is any error in any underlined part and indicate your response in the Answer Sheet against the corresponding letter i.e., (a) or (b) or (c). If you find no error, your response should be indicated as (d).

A) If a thing B) is worth doing at all
C) it is worth done well. D) No error
 
Answer & Explanation Answer: C) it is worth done well.

Explanation:

Error is in third part. Since “doing” was used in second part it should be followed by “doing” in third part as well instead of using “done”. Such repetitive figure of speech is used in
English grammar to create emphasis. This sentence indicates that a thing that is worth doing is also worthy of doing well. Here worth is the noun that must be followed by the verb doing.
