यदि अपस्फीतिकारक पहले वर्ष 20 प्रतिशत बढ़े और दूसरे वर्ष 20 प्रतिशत घटे तो दो वर्षों के बाद मूल्य स्तर में कुल परिवर्तन क्या होगा?
If the deflator rises by 20 percent in the first year and falls by 20 percent in the second year then what is the total price-level change after two years?
Explanation opens after your attempt
B. 4 प्रतिशत गिरावट4 percent fall
Concept
The total factor is \(1.20\times0.80=0.96\) so the price level is 4 percent lower. Percentage rises and falls are asymmetric.
Why this answer is correct
The correct answer is B. 4 प्रतिशत गिरावट / 4 percent fall. The total factor is \(1.20\times0.80=0.96\) so the price level is 4 percent lower. Percentage rises and falls are asymmetric.
Exam Tip
कुल गुणक \(=1.20\times0.80=0.96\) है इसलिए मूल्य स्तर 4 प्रतिशत कम होगा। प्रतिशत वृद्धि और कमी असममित होती हैं।
