privacy - How to do Factory Reset

I know the topic has been covered here. But this is something different. I got a Tablet in my workplace to work with. It has a primary email Id for which I don't know the password. So to remove this, I clicked on remove account, but it says it can't be done. Only a factory reset has to be done to remove this Id. I tried adding an alternate gmail id, but still it considers the same Id for which I don't know the Password. So I tried to look out for factory data reset option in Sdcard and Device storage. But there is no such option there. I tried all over the net, but couldn't find anything useful.

Can someone help me on how to do a factory reset without the factory reset option?

NOTE: The Tablet looks like an ipad with same kind of button. I am not sure about the name of it, but my guess is "MID".
