The price of sugar is increased by 25%. By what percentage should a family reduce its consumption of sugar so that its expenditure remains unchanged? / चीनी का मूल्य 25% बढ़ जाता है। कोई परिवार चीनी की खपत कितने प्रतिशत कम करे ताकि उसका व्यय अपरिवर्तित रहे?
1.
25% / 25%
2.
20% / 20%
3.
16.67% / 16.67%
4.
30% / 30%
Correct Answer: 20% / 20%
If the price becomes 1.25 times, consumption must be multiplied by 1/1.25 = 0.80 to keep expenditure constant, i.e. a reduction of 20%. / यदि मूल्य 1.25 गुना हो जाए, तो व्यय स्थिर रखने हेतु खपत 1/1.25 = 0.80 गुना करनी होगी, अर्थात् 20% की कमी।
