It is based on inverse proportion or product constancy concept. Reduction in price 20% amount of sugar will increase 25% It means, 25% = 6 Kg. So, Initially, total Sugar = 6 × 4 = 24Kg. Thus, Original price of the sugar was, $\frac{24}{24}$ = Rs. 10 per kg. Note: Let initial price of 100 kg Sugar was Rs. 100. Now, 20% decrease in rate then rate of 100 kg sugar would be Rs. 80. So, Rs. 80 = 100 kg sugar. Rs. 1 $=\frac{100}{80}$ kg sugar. Rs. 100 $=\frac{100 \times 100}{80}$ = 125 Kg sugar. Increment in sugar = 25 kg. % increment $=\frac{25 \times 100}{100}$ = 25%. Means 20% rate decrease, 25% of consumption increase.
