Concept :-
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,
24024
= 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 = 10080
kg sugar.
Rs. 100 = 100×10080
= 125 Kg sugar.
Increment in sugar = 25 kg.
% increment = 25×100100
= 25%.
Means 20% rate decrease, 25% of consumption increase.
