### Dear rajuharan@hotmail.com

Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

You have asked extremely intelligent question and we would like to understand where you are getting stuck on this question, once we are clear, we would be able to explain things better. For such type of problems, find the image distance of first lens then use it as object distance of the second and moving on find the focal length of the third. However, this logic seems to be falling short when we are trying to solve and so we would like to know where you are getting stuck and we might be able to pick it from there and help you out.

Regards

Topperlearning Team.
