Why this answer is correct
The correct answer is C. (30). \(x^2+156=1057\) gives \(x^2=901\), not a listed perfect square, so this is a data-error type question. In exams, check consistency before solving.
Exam Tip
\(x^2+156=1057\) से \(x^2=901\) नहीं, इसलिए विकल्प जाँच की बजाय समीकरण सुधारें: सही वर्ग के लिए \(x^2+156=1056\) चाहिए।
