What is the greatest 5-digit palindrome n such that 7n is a 6-digit palindrome??
This problem appeared as a problem in Regional Exam of Secondary Category 2020. I am in junior category. But, this seems as an easy problem, that's why I tried to solve this problem and I got n=88088 as my answer. But I don't have any explanation. I don't even know whether it is correct or not. Please let me know about the proper explanation. I am new to this forum, Please forgive me if I did any mistake.
