There will be 3 images formed .If the man is standing symmetrically then first image will be behind mirror M1 .2nd will be behind M2 . 3rd will lie on the angle bisector of the mirrors .This image will be behind both M1 and M2 .

Now I don't think in any of the images , the man will be seen using his right hand .He will be seen combing with his left hand .But this is incorrect answer .

What is the mistake?

Try sketching the layout. What will this image look like?

Have you ever looked into the corner of two mirrors at right-angles? Its a reasonably common find in elevators.

Do we assume man to be facing one of the mirrors Or Is he facing the corner of the mirrors ?

No . Never had the opportunity to look in right angled mirrors .

It simply says 'how many images will be seen'. i.e. no assumptions need be made.

BTW, you noted that yourself in your answer: 3 images will be seen.

Pretend you are hovering over the man's head. Sketch the diagram of the images:

From your posts it seems that this 3rd image behind the corner is the one where the man is seen using the right hand . Is that the case ?

I am not saying that at all.

I provided a sketch for you to mark up.
