Question

The price of sugar fell by 10%.if the same amount of money has to spent on sugar as before , by how much percent must the consumption of sugar be increased​

Answer 1

Answer:

Let the original price of the sugar be Rs100

And the consumption be 1kg

Then total expenditure will be Rs100×1=Rs100

Now, when price is increased by 20 %, then new price is Rs120

Then new expense will be Rs120×1=Rs120

For expense to be same to Rs100,

% decrease in sugar consumption = 120

120−100 ×100=50 /3

 =16.66=approx. 17 %
