The problem written in the image is in Marathi and appears to involve arithmetic or a word problem. Let me transcribe it and provide a detailed solution:

Problem Transcription:

1. एका पुस्तकाच्या 9 भागांमध्ये 250 पाने आहेत.
   (A book contains 250 pages divided into 9 parts.)

2. त्यापैकी 50 पाने वाचल्यास उरलेल्या पानांची संख्या किती?
   (If 50 pages are read, how many pages remain?)

Solution:

1. Total number of pages in the book = 250.

2. Pages read = 50.

   To find the number of pages remaining, subtract the pages read from the total pages:
   $\text{Remaining pages} = \text{Total pages} - \text{Pages read}$
   Substituting the values:
   $\text{Remaining pages} = 250 - 50 = 200$

Final Answer:

The number of pages remaining is 200.
