Question

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

Answer 1

Step-by-step explanation:

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=

3

50

=16.66=approx. 17 %
