Question

the price of sugar has decreased by 20% . the consumption also decreases by 4% . Find out by what percent overall expense can sugar has reduced
​

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 =120120−100×100=350=16.66=approx. 17%
