By seeing the question we can use the formula
Expense = Price × Quantity
Calculation part using the above formula
Consider the initial expenses as Rs.100 on sugar
If the price rises by 25%
New price = (100 + 100 × 25%) = 125
Rs. 25 must be subtracted from Rs. 125 to keep the cost the same.
= 125 - 25 = 100
Decrease in the consumption = 25/125 × 100 = 20%
The price of sugar has increased by 25%. If a family wants to keep its expenses on sugar unaltered, then the family will have to reduce the consumption of sugar by?
Sugar has gone up in price by 25%. A family must cut their sugar consumption by 20% if they wish to maintain their current sugar spending.
