Correct Answer

A. (132)

Step 1

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.

Step 2

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.

Step 3

पहला भाग (1320) और दूसरा \(3\cdot990=2970\) नहीं; सही दूसरा \(3\cdot990\) है, अतः मान ऋणात्मक होगा और विकल्प त्रुटिपूर्ण हैं।
