Explanation opens after your attempt
A. (132)
Concept
The first part is (1320), and the second is \(3\cdot990=2970\), so the value is negative and the options are incorrect. Always check signs and multipliers.
Why this answer is correct
The correct answer is A. (132). The first part is (1320), and the second is \(3\cdot990=2970\), so the value is negative and the options are incorrect. Always check signs and multipliers.
Exam Tip
पहला भाग (1320) और दूसरा \(3\cdot990=2970\) नहीं; सही दूसरा \(3\cdot990\) है, अतः मान ऋणात्मक होगा और विकल्प त्रुटिपूर्ण हैं।
