Question

I am doing sums.
a)Sums are done by me.
b)Sums are being done by me.
c)I must be doing the sums.
d)Sums must be done by me.

Answer 1

Hint: We use passive voice when we want to pay attention to the recipient of the action or the subject affected by the action.

Complete step-by-step answer:

In the above-given question, we can understand that X is doing sums at the moment. The given action is in present continuous form. Hence, the answer should be in the present perfect continuous form.
We need to follow certain rules while changing a sentence from active voice to passive voice-
1)We use ‘by’ when both the subject and direct object are mentioned in the active voice.
2)We interchange the original position of the subject and the object.
3)We always use the Past participle or the 3rd form of the verb.
Let’s look at the given options:
a)Sums are done by me- The given statement is in present perfect form. Hence, it is an incorrect option.
b)Sums are being done by me- The given statement is in present perfect continuous form. Also, the structure of the sentence is accurate. Hence, it is the correct option.
c)I must be doing the sums- The position of the object and the subject has not been interchanged. Hence, it is an incorrect option.
d)Sums must be done by me- The use of ‘must’ is inappropriate and unnecessary. Hence, it is an incorrect option.
The correct answer is Option ‘b’.

Note: In many cases, ‘with’ or ‘to’ is used in place of ‘by’ depending upon the meaning expressed by the sentence in the active voice.
