Introduction
When the price of a commodity increases, consumers tend to reduce their consumption of that commodity to maintain their expenses. This principle is known as the law of demand. In this scenario, we need to determine how much a customer should reduce their consumption of salt to avoid increasing their expenses after a 25% increase in salt prices.
Calculation
Let us assume that the original price of salt is Rs. 100 per kg. After a 25% increase, the new price of salt would be Rs. 125 per kg. To maintain their expenses on salt, the customer needs to spend Rs. 100 on salt after the price increase.
The customer can achieve this by reducing their consumption of salt. Let us assume that the customer initially consumed x kg of salt per month. After the price increase, the customer needs to consume y kg of salt per month to maintain their expenses.
To calculate y, we can use the formula:
Original expenditure = New expenditure
Price per kg * Quantity consumed = Price per kg after increase * New quantity consumed
Substituting the values, we get:
Rs. 100 * x = Rs. 125 * y
y = (100/125) * x
y = 0.8x
Therefore, the customer needs to reduce their consumption of salt by 20% (100% - 80%) to maintain their expenses on salt after a 25% increase in salt prices.
Conclusion
In conclusion, when there is an increase in the price of a commodity, consumers can maintain their expenses on that commodity by reducing their consumption. In this scenario, the customer needs to reduce their consumption of salt by 20% to avoid increasing their expenses after a 25% increase in salt prices.

Let's assume the initial rate of salt was Rs 100 per kg, then after 25% increase the new rate becomes 100+( 25% of100 ) kg i.e 125/kg.
Now let's assume customer was buying 1 kg of salt every month for Rs 100, so after the price got increased the customer will have to pay Rs 125 for the same amount of salt i.e 1 kg.
So to avoid increasing his expenses on salt, the customer needs to reduce his consumption by a certain percentage, so let's assume he reduces his consumption by x%.
Hence, the new quantity of salt that the customer will buy is (100-x)% of the original quantity of salt i.e (100-x)/100 * 125 kg, Now as we need to find the value of x that makes the cost of this new quantity of salt equal to Rs 100, we can set up the equation to solve for x i.e (100-x)/100 * 125 = 100.
After solving this equation wet get 20% as the value of x which means that the customer needs to reduce their consumption of salt by 20% to maintain their expenses on salt at Rs 100 after 25% increase in its price.
