A number is increased by 20% and then decreased by 20%. What is the net percentage change in the number?
एक संख्या में 20% की वृद्धि की जाती है और फिर 20% की कमी की जाती है। संख्या में शुद्ध प्रतिशत परिवर्तन क्या होगा?
Detailed Solution & Logic
Correct Answer:
4% decrease / 4% कमी
Explanation:
मान लेते हैं संख्या 100 है। 20% बढ़ाने पर यह 120 हो जाती है। अब 120 में 20% की कमी = 24, इसलिए नई संख्या 96 होगी। अतः 100 से 96 होने पर 4% की कमी हुई।
