Question

Change this into active voice [Shreyash was given work] (with proper explanation )

Answer 1

Shreyash was given work (by Atharv).

The sentence is in Simple Past Tense.

So, the Passive Formula will be:-

Subject+was/were+V3+Object

There is no mandatory object in the sentence so let's add a mandatory object Atharv. So the sentence becomes-

Shreyash was given work (by Atharv)

For converting the sentence into active we need to interchange the places of subject and object. So here is your answer-

Atharv gave work to Shreyash.
